I had similar problems when moving upto 3.8.1. The previous sysadmin responsible for RT had failed to upgrade the DB properly when going from 3.6.5 to 3.8.0 some time back. All our attachments went screwy too when I tried to upgrade to 3.8.1.
In the end what I did is dump the database before upgrade in case I need to go back. Dumped all attachment records to disk via perl, ran the RT upgrade scripts and then updated the attachments table from the ones I had dumped out earlier. This then made all the attachments become working again. RT itself also seemed to get a performance boost !YAY!. And the two ALTER entries in the upgrade script I found as well, Prior to running the upgrade I removed the ones that weren't binary columns e.g. VARBINARY so removing the lines which mentioned something like LONGBLOB. When you use mysqldump to backup the database you just need to make sure to place this "--opt --default-character-set=binary" in the commandline arguments. That will mean it exports in binary mode to avoid corruption. *Regards, Aaron Guise 07 838 7793 027 212 6638 aa...@guise.net.nz* On Wed, Sep 16, 2009 at 7:54 AM, Justin Hayes <justin.ha...@orbisuk.com>wrote: > Hi guys, > > I'm just testing an upgrade from 3.6.3 to 3.8.4.
