Migrating ServiceDesk to a new server old one uses MySQl and new install there is no mysql option

Thanks in advance, we are migration to a new server. We are on version 9 build 9000 the database is MySQL. On the new server the installer doesn't have MySql as a choice. It has only postgresql and MSSQL. In this scenario how do I migrate to the new server?

I found this topic helpful

Also I could not find an installer for version 9 build 9000 so that i can install that on the new server and patch it to the latest version.

when I try to update version 9000 to 9040 I get an error message

" JRE upgrade is pending. Start ServiceDesk server once and try applying the patch."

Any help is highly appreciated.
