Apologize for a new post on this since I see that similar posts are out there already, but I have not found a clear cut answer on any of them. When I try to upgrade (locally OR remotely) from ee 1.6.7 to 2.x I keep running into database errors regarding this file:
Filename: updates/ud_200.php
They all have to do with either a duplicate key or unknown column in a table. Here is my latest one:
A Database Error Occurred
Error Number: 1054
Unknown column ‘recent_trackback_date’ in ‘field list’
SELECT `recent_trackback_date`, `entry_id` FROM `exp_weblog_titles`
Filename: updates/ud_200.php
Line Number: 647
I’ve followed the upgrade instructions to the letter. Any advice or if anyone can point me to a thread with the solution is greatly appreciated.
