Fixed this issue and got the DB converted but now I hit a known bug:

Help would be appreciated  

Bumping this as I have the same error during the upgrade process. The fix doesn't appear to have been implemented yet so if someone could contact me with the details it would be appreciated. The access info in my account has been updated.

Just an update. Tried the CLI converter and it got past the posts table but when it gets to rss_imported it gives this error:

Processing: rss_imported                                                                 43%
Error: Specified key was too long; max key length is 1000 bytes
File: /system/Db/Db.php
Line: 198

Trying to do a test upgrade of our board from 3 to 4 and after it passes the system checks, it starts the UTF-8 conversion tool.

Gets to the posts table and never gets any further. I've restarted the tool multiple times and the same thing happens.

We have just over a million posts but I've given it 2+ hours and it never moves beyond that table.

Looking at the actual database in phpMyAdmin, the new x_utf_posts table appears to be full and has the number or records it should.

Any ideas what could be causing it to hang on this table?
