Just completed Google Apps (Mail, Vault, Drive, Sites) the whole lot to Office 365. A lot of scripting, third party tools, and patience required.

Edgar Vicioso You're in great hand with Antonio Maciel De Vargas. I've worked with him and the BitTitan team. Also if you need help with Google Sites or Drive migration please let me know as I know plenty of folks Down under :-) Also here are some tips on what does and what does not get migrated with the BitTitan tool: BitTitanWhat migrates and what doesn’t for Google Mail\Vault to O365 migrations https://community.bittitan.com/kb/Pages/What%20items%20are%20migrated%20with%20MigrationWiz.aspx Google Apps: Inbox, Folders/Labels, Email, Muted Email (as regular email), Contacts, Calendars (including links for Google Hangouts within calendar meetings).o Note: Links for Google Hangouts are a new default feature added to Google Meeting. Microsoft Office 365 doesn't have the corresponding property to map. Therefore, when migrating to Office 365, the links for Google Hangouts are added to the beginning of the meeting description body text on Office 365.Google Drive: Folders, Shared Folders in your Drive, permissions, Google Apps native files except Google Forms, Code Files (Xml, cs, cpp, h, etc.), Documents (docx, doc, odt, csv, pdf, etc.), Images (png, jpg, etc.), Executables (exe), Videos (avi, mp4, etc.), Audio Files (mp3, wave, etc.). Typical Destinations: OneDrive for Business, Google Drive.Google Sites: Files on Google Sites that are of the "File cabinet" page type can be migrated using MigrationWiz to SharePoint Online document libraries. The migration includes both documents and document permissions.Google Vault (Source Only): Folders, Emailhttps://community.bittitan.com/kb/Pages/What%20items%20are%20not%20migrated%20with%20MigrationWiz.aspx

We used the Google Drive Inventory Tool to collect all the Drive Data. Watch out if you have a large no of users or users with very large (we had users that had close to 1TB of data) that can take a long time to get the output from the tool. Make sure to check out the limitations on what will and what will not get transferred\migrated https://support.office.com/en-us/article/SharePoint-Online-software-boundaries-and-limits-8f34ff47-b749-408b-abc0-b605e1f6d498?ui=en-US&rs=en-US&ad=US

The tool was provided by the Fasttrack team.

The migration was from Google Apps (Gmail, Drive, Sites and Vault) for over 7000 users. We helped our customer with the Identity, Change Management and Schedule for the migrations. We used FastTrack services for mailboxes less than 40 GB. FastTrack uses the DELL tool that has limitations and we also identified some bugs that later got fixed but had to run delta passes for migrations as it did not move attachments prior to the bug being fixed. The tool had its limitation and could migrate about 2.5GB per day per user. For any mailboxes over 40GB we used BitTitan MigWiz and it did not have the throttling limitation as the DELL tool did. For Google Sites to SharePoint Online we used Metalogix Content Migration tool for Google Apps (they no longer sell this tool). The tool was very limited in what it can do and based on numerous calls with the vendor. They mentioned its hard to keep up with the Google API changes which breaks functionality of the tool thus they are not planning any new development on the tool. Most of the Google Sites had data embeded into the sites which was pointing to users Google Drive and most content was also pointing to users Google Drive. We used ShareGate for this part of the migration and it worked out pretty good. We had a couple of hickups but ShareGate support was very prompt on helping us resolve the issues. For Vault migration we used BitTitan as well and it was great both the product and support we recieved from the BitTitan team.

Hi Luke, We did not take the big-bang approach as I don't think that was the most effective way especially with over 7000 users and they were in different parts of the world. We started with the identity piece and did due dilligiance work when it came to thier network, bandwith, firewalls and user expiernece. We ran 2 pilots, the first was the a small group of IT folks and then got about 70-80 users from various departments, regions of the company. We did mail first with a 2 step\pass migration process. Migrating 30 days of mail, all contacts, All calendar (upto a year) and in the 2nd pass migrated the remaining mail. The duration varied based on the size of the mailbox. We encourged the client to migrate users in group that were tied to particular sites and business units as they were sharing info via Google Drive and Sites. We ran mail migrations for about 10 days before we started Sites and Drive migration. We could only start Vault migrations for users once they had completed thier mail migrations or else they had the risk of duplicate data in thier Archive or Mailbox.

Hi,

I have been looking forward to migrate Google apps to O365. Please let me know is there any way to do this migration using api's instead of using tools.
Help me to start this migration without any thirdparty tools.

Hi Faiza,

I am working in a migration scenario similar as yours, 11K mailboxes, using FastTrack.
We are considering using BitTitan to migrate data from Google Vault to O365, just concerned about Google Throttle limitations, did you have any problems downloading the matters to the Google Vault Extractor VM? Can you remember how much data in average per day were you able to extract from Vault?

FastTrack will also migrate Google Drive. Did they help you to remediate the files according to OneDrive limitations, such as invalid characters? or was that the reason you used Sharegate?
also, how did you manage to use Sharegate and FastTrack to migrate Google Drive?

Thank you so much.

  Edgar Vicioso, Nuno is correct about the using the BitTitan tool for the Google Vault migrations. With the licenses that you purchase BitTitan's assistance to help with you the migration is included. So please leverage them.
  
  For Google Drive to OneDrive for Business migrations it's a little more complicated. We used Sharegate to move the Google Drive data that was linked within a Google Site as we were migrating Google Sites as well. Sharegate is a great tool for that. There are not that many tools out there when it comes to migrating Google Sites to SharePoint. The tool we were using is no longer sold due to having so many limitations and bugs. We ended up building majority of the SharePoint sites and used ShareGate to move the OneDrive data to SharePoint libraries and pages. FastTrack does not assist in remediation. It just gives you daily reports on pre-flight and post migration reports for success and failures. You can request a detailed report but if your uses have large drives those are pretty large reports to sort through.
  
  Let me know if you have any additional questions and good luck with the migrations.

    Thank you Faiza for replying. Much appreciated.
    
    I was interested in knowing how much data we could extract from Google Vault per day, to be able to give our client an estimate of the effort required to move their archives to O365. We have asked BitTitan about it but as there are too many components in their Vault migration solution, they recommended us to do pilot to get a more accurate estimation. The good news is that our client approved it.
    
    Thank you so much for sharing your experience.
    
    Best Regards.

  Hi Edgar, about throtling with the BitTitan MigrationWiz, you will not have that problem, but the best way is to contact BitTitan directly that they will help you.

What scripts and 3th party tools did you use? I used MigrationWiz for the email and ShareGate for migrating Google Drive to SharePoint / OneDrive, worked great!

  For mailboxes over 40GB and Vault migrations we used MigrationWiz as well. Google Drive migrations were handled by FastTrack but I believe they used a DELL tool. We used ShareGate as well for Google content that was linked back to Google Drive as we managed and migrated Google Sites to SharePoint online.

    I thought Fasttrack Center wasn't intended for email and data migrations. :mansurprised:

Ya verificaste en Microsoft Flow, allí tienen funciones que puedan ayudarte.
Aunque también sería interesante una aplicación o un servicio que pueda hacer puente entre Google Apps y Microsoft

    Hi Faiza
    
    That's a very impressive transition.
    
    Can I ask did you go big-bang transition to Office 365, or incremental? If big-bang, how did you support the transition for so many users? If incremental, what order did you deploy the Office 365 solutions?
    
    How did you 'sell' the change to the users? I guess that many would have been reluctant to switch away from Google Mail, Calendar and Drive?
    
    Thanks,
    
    Luke
