Which Databases are needed

[Dknelson]

I switched my forum from VBulleting to Invision two or three years ago.  When I look at PHP MyAdmin, I have several databases and I know that at least a couple of left over from VBulleting.  Does Invision use these are can some be deleted?

I wonder if _forums and _forums2 can be deleted.  Also, ipb one appears to be completely empty.  Now sure why it's there.

You should check the conf_global.php file in the root of your installation to determine which DB is used by your Invision installation - the 'sql_database' entry is the name of the DB used.

And to add to the above, definitely make backups of the databases you do decide to delete just in case you want to use or revive them in the future.

You can never be too careful and it would suck if you lost a lot of content from previous forums.

I've identified which current. database is used.  What I wonder though is why the database for VBulletin was left there after I swapped to Invision.  Does it still pull any information from the old one?

It was left behind because it wasn't deleted by you.

And no, it doesn't pull any information unless you have something in place that is doing that.

Back them up, delete them, restore if there any issues.

Thank you.

When you convert from one software program to another, it will typically just COPY the data from the old one to the new one.  This is intentional because if the conversion goes wrong or if there are unexpected problems, you would be very upset if your original data was destroyed as part of the process.  

Another option short term if you don't know if it's used is to rename the database to something else.  If nothing breaks, then delete it.  But if something does break, it is typically faster to rename the database back to the original value instead of doing a restore.
