I’m migrating from phpBB this needs to be done from Xenforo 1.5.x because 2.x does not have the function to do it. I want to run version 2.x but how to continue. I have tested the import from phpBB to Xenforo a few times and import seems good. But now i need to make sure every option is checked and all permissions and user groups are good. But do i this on version 1.5.x or 2.x if i do this on 1.5.x then i need to recheck everything again on 2.x. If i check on 2.x only then i my miss something in setting or something else. Is it save to check everything on 2.x or should i not do this?
