SharePoint Online Permission migration between tenants

Vikas Shah 21 Reputation points


We had two Tenants:

we procured another domain called and added the new domain in the tenant. After that we migrated everything from to tenant. Post migration everything of 123 and abc is changed to

everything is ok. However, we stuck on the sharepoint site.

One of our sharepoint site located at was migrated to with a 3rd party tool.

Post migration we realized that site is migrated but the permission got screwed. We have multiple document library and subsites in that particular Sharepoint site. in which the permissions were given using custom Sharepoint Groups and some of the users got via direct permissions.

However, in the migrated site on XYZ, the permission never got transferred properly. we can only see the owners permissions, however, the custom Sharepoint groups, members, custom permissions on the SharePoint Document libraries and subsite, never got any permissions. Due to which most of the users aren't able to access the site the way they used to do it.

Is there any way, we can export all the permissions (Site, Site collection, Lists, Document library, subsites, Item like folders/files) and then import it all (of the custom sharepoint groups isn't exist, it should create) in the new tenant so that it will start working.

I am ok to use Powershell or any 3rd party free tool to achieve this.

Awaiting response,

    Hi @Vikas Shah,

    As per my knowledge, I'm afraid the answer to this question is NO. I haven't heard any OOTB way which can migrate permissions between tenants. This is also why migration between tenants is not recommended by Microsoft. It appears that you have to rebuild the permission infrastructure in your new tenant. As to 3rd party tools like ShareGate, I am not sure if this can be achieved from them. You can contact 3rd party support to confirm your scenario with them.
