Dear All,
Background,
Due to EOSL issue on APPEON for PowerBuilder2015, we purchased license of APPEON PowerBuilder 2019r2, in order to migrate current programs to PowerServer version with maintenance.
When we prepare development environment for code migration and test, we learnt we cannot upgrade PowerServer by installation, and both version cannot be co-existed. So we have to remove current setup with APPEON for PowerBuilder 2015, and then install the PowerServer (PB) version, and apply license and deploy all the programs.
Problems,
How to perform upgrade and license transfer between the versions in our situation? And is rollback plan available?
Consideration,
Since it is production environment, we would perform the upgrade during non-office hours, to minimize service impact.
(added) We do not have spare server on production environment to allow the versions co-existed, for e.g. DEV server cannot be used for the purpose as it was limited from accessing production DB. It would be a BIG project if we have to negotiate with security team.
So may we have your advices and experience sharing with our situation? Thanks in advance.
Best Regards,
Charlie Wong
