Migrating from HSQLDB to MySQL on Version 3.0

I have inherited a TeamCity installation on version 3.0 and can no longer access the database on startup:

I get a 404: error in the browser.   This just started happening.  There were no changes made to the system other than adding some new users

In the stdout log I see the error that it can not create the bean with name 'buildserver'

I feel that there is an issue with the HSQLDB and I wanted to migrate it to MySQL (this is the only other supported DB i believe on this version)

I have tried to use the migrateToMySQL.bat utility but then I receive the error

Done.


Any thoughts why it can't access the HSQLDB? Why SA is not found?

I did notice the buildserver.data file was exactly 64MB (65,536 KB).  That did seem odd almost as if the DB max'd out at 64MB and it was Full.  I don't much about HSQLDB....

Thanks for any tips
