SharePoint Migration of On Premise Subsites to SP online 2020

Occasional Contributor

Hi Team,

We are currently migrating Site Contents from earlier Sharepoint to SharePoint Online. (Using ShareGate Tool)



Destination(Communication Template):


There might be huge documents with a different set of user Permissions which I need to cross-verify.

Please let me know if there is any way to validate it. Or there will be smooth migration which would retain Permission Levels.


Will be thankful for your support

You will find that migrating the permissions with ShareGate(or any tool) is a bit of a lottery, reason being is that AD groups and users may not exist in SharePoint Online. You can map users that don't exist, I have not tried it with groups. Generally historic permissions are not always right or a a bit of a mess. 


In every migration that I have done I have taken the opportunity to start a fresh and reset the permissions with confirmation from the site owners about what they should be.
