I am a new ShareGate user. While using the tool last few days, I noticed that it does not allow the language to be changed. We have a tenant in another country and we use English language. Because the tenant is in another country, some of the default folders, lists or libraries that are created show up as a different language. I had to check in the individual folder/list/library property to see which folder I want to use as my source or destination before action for the migration.
There should be a possibility to allow the language to be selected for users.
