ServiceDesk Plus upgrade fails from build 15200

ServiceDesk Plus upgrade fails from build 15200

Hello,

I've got an issue upgrading from Build 15200 SP3 to any build beyond it. I've tried installing 15200.6 as it's a newer service pack but as it's the same build number so it won't allow the install.

When installing a newer build such as the latest 15280 the install fails near the end while or after doing DB Upgrades.

I've got a 7zip of the logs folder so can get files needed, I've now rolled back my server to a position before attempting the upgrade.

Regards

Jake
