[rt-users] RT 3.8.8 -> RT 4.0.4 schema.mysql error

[Ronald J. Yacketta]

We ran into the following schema.mysql error during our upgrade from 
3.8.8 to 4.0.04, after some investigation it appears that it stems from 
using RTFM in 3.8.8.

Processing 3.9.8
Now populating database schema.

DBD::mysql::st execute failed: Table 'Classes' already exists at 
/root/src/rt-4.0.4/sbin/../lib/RT/Handle.pm line 517.

Our solution was to re-ran 'make upgrade-database' using 3.9.9 as the 
version upgrading from.
