I'd like to get some feedback on my proposed general direction. I shall first lay out the current landscape and then describe the plan going forward. Any feedback is welcome and thank you in advance.
We have 1 Office 365 subscription; however it appears as 2 tenants
This is because we began online services back in the day (2009/2010) with BPOS (Business Productivity Online Suite) which was the precursor to Office 365.
Because we were early adopters, our tenant is oddly comprised to 2 domains
Our old site collections begin with xxxxxx-portal1.sharepoint.com
Our newer site collections begin with xxxxxx.sharepoint.com (no portal1)
This also means we have 2 root sites (portal1 and non portal1)
One issue I have seen with the dual domains is that we cannot utilize the create a list from an existing list option
If I'm in a xxxxx.sharepoint.com site, I cannot create a list from another list that lives on a xxxxx-portal1.sharepoint.com site
In the past I had issues creating powerapps from xxxxx-portal1.sharepoint.com sites as well
I believe this have since been resolved
Unfortuately, 99% of our data lives on the old xxxxx-portal1.sharepoint.com sites and sub sites
Additionally that 99% of data is nested in sub, sub-sub, sub-sub-sub sites within a single site collection
Where I'm trying to get:
The plan is to create new site collections for each functional area (Technology, Marketing, HR, etc) in their own separate site collections
The new sites would have the xxxxxx.sharepoint.com domain
We would eventually deprecate all xxxxxx-portal1.sharepoint.com sites after the data is copied to the new locations
We will utilize Hub sites for each functional area to share general info with all staff; however, each function area within a major arm of the company will also have its own modern Team site where they do day to day work
One of my major questions with this is...should we attach Microsoft Teams to those functional Team sites or should Microsoft Teams NOT be used for permanent type situations?
Another major question is....what happens if we do attach a Microsoft Team to a functional area and they decide they don't want/need a MS Team?
As I understand it, we cannot remove a Microsoft Team from a Team Site without deleting the entire site collection and its contents
Thank you for any suggestions you have. Also, is there anyone else in the same boat as us (early adopters with basically 2 types of URL's in a single tenant? [xxxx-portal1.sharepoint.com and xxxx.sharepoint.com] ?
