Manually manipulating the database is never a good idea - there is a lot of interconnected data and tables.

Deleting content should be done via the regular UI (that won't reset IDs though).

So is that a good idea to do a clean installation and then import user tables?

Maybe I'll live with those IDs or find a way to remove IDs from urls completely

If you want to retain some content (e.g users) then an XF to XF import would probably be the best option.

Delete the content you no longer want from the source forum, then run the import and just import the users.
