The Server extension allows ShareGate Migrate to make one call to get a file and all its versions simultaneously. Without the extension, ShareGate Migrate must make one call per version.
For example, if you have 100 files to copy, and each of those has 20 versions:
With the Server extension - 100 calls are required.
Without the Server extension - 2000 calls are required.
The extension also helps to lift some migration limitations and helps to improve performance when migrating to Microsoft 365.
