How to migrate mailbox with over 500 GB - Migration from GWS to M365
Hello, I am trying to migrate GWS mailboxes with over 500 GB to M365 utilizing third-party tool. I have around 50 mailboxes over 200 GB and 10 mailboxes over 500 GB. With third-party tool, I can migrate Gmail to archive mailbox of M365. and I am aware of the fact that it needs auto-expanding feature of archive mailbox. So I have enabled auto-expanding feature for those archive mailbox. However, the thing is the daily growth rate and It cannot exceed 1GB/day as I noticed through below link. https://learn.microsoft.com/en-us/purview/enable-autoexpanding-archiving#more-information The link says like this. Auto-expanding archiving is supported only for mailboxes used by individual users or for shared mailboxes with a growth rate that doesn't exceed 1 GB per day. Is there any way to speed up the growth rate? And provisioning speed also matters. https://learn.microsoft.com/en-us/purview/enable-autoexpanding-archiving#before-you-enable-auto-expanding-archiving the link goes like under. After you turn on auto-expanding archiving, an archive mailbox is converted to an auto-expanding archive when the archive mailbox (including the Recoverable Items folder) reaches 90 GB. It can take up to 30 days for the additional storage space to be provisioned. Is there any way to shorten the days for the additional storage space to be provisioned? How can I overcome this circumstances? or is there an other method to do this? Thank you in advance.How to Enable Exchange Online Mailbox Archives Based on Mailbox Size
This article explains how to use PowerShell to enable Exchange Online archive mailboxes after primary mailboxes reach a certain size. Some simple PowerShell code checks the mailbox size and if it’s too large, enables the archive and assigns a mailbox retention policy containing a default move to archive tag to move items from the primary to the archive mailbox. Some Azure Automation would make sure that the script runs periodically to keep mailboxes in good health. https://office365itpros.com/2023/01/03/archive-mailboxes-based-size/
