What I plan to do is to install FRESH INTEGRATED installation of PP in separate directory.
1 .Then I guess I need to populate the ubb threads user table with the entries from the existing PP user table ( I may have to alter user_ids and similar).
1.1 If username from the forum matches a username from PP, the accounts would be merged.
1.2 usernames that do not have a match in the forum table, would have a new forum account created for them. (Q: in UBB.Threads what table get affected when one creates an account? I know the user table gets a new entry, but does any other table? )
2 .Then I can extract the data from the remaining PP tables and import them into the new installation of PP.
2.1 I will have to change the config table and put the appropriate paths
2.2 Change the photos table with the new user_id
2.3 Rename the photos from the `data` directory with the proper new user_ids
Am I missing anything
