duplicate threadid

[Joe M.]

Doing install of 3.5.1 from 3.0.7 During Step 6 of Beta 1 upgrade get an error:

Database error in vBulletin 3.0.10:

Invalid SQL:
ALTER TABLE thread CHANGE postusername postusername VARCHAR (100) NOT NULL DEFAULT '';

MySQL Error : Duplicate entry '98825' for key 1

I do infact somehow have two threadid's that are the same. What is the best action to take here? Delete one of the entires? Delelte both and all corresponding references to the threadid? Table repair?

2 hours later.....

I went ahead and deleted the 2 thread rows. Couldn't find any other occurances of the threadid in the database. Hopefully that works out. I couldn't hold off the installation for many more hours.
