Migrate a few user from Pro to CE (including libraries, share links, etc.)

Hello,

i want to migrate a few user from seafile pro to CE.
I want to keep the shares/groups/share links /etc.

I have done some research and i think the only way to do this is probably to copy the database and the library id related subfolders from the blocks commits and fs folders.

Or does anyone have any other ideas?
I would like to run pro and CE in parallel, so a complete migration is not a solution.
