Hi;

  PB 12.x is long deprecated and does not have any cloud features either. You need to be on Appeon PB 2022 to achieve cloud deployment & use.

Regards ... Chris 

Remote Desktop Web (RDWeb) can run your PowerBuilder app unchanged.

The lowest-cost way to go to the cloud is PowerServer.  Running remote desktop in cloud is super expensive.  So you have to not just look at the difference in effort of implement remote desktop vs. PowerServer but also the on-going costs to get total cost of ownership.

With that said, upgrading from PB 9 to PB 2022 R3 shouldn't be too much effort.  The key thing is you got to deal with converting ANSI to unicode.  Once you get on PB 2022 R3, then deploying as PowerServer project type should be minimal work.  Most customers I've seen get their app running within several weeks.

PB 9 was released in 2003. It does not support REST API's, Unicode, nor can it utilize current database drivers. With each passing year, you run an ever-increasing risk that your PB 9 application will no longer work due to changes being made in the Windows operating system. It is likely there are very few fellow PB developers that have knowledge of or experience with PB 9, which limits your ability to obtain advice/help.

It may be time for you to consider upgrading.

Here are links to a couple of current PB documentation topics that you may find useful:

    https://docs.appeon.com/pb2022r3/pbug/upgrading_targets.html

    https://docs.appeon.com/pb/upgrading_pb_apps/UpgradingPowerBuilderApplications-Overview.html

The Migration Assistant utility (described in the first link) will check for obsolete syntax without migrating your target(s) to the new version.

The Upgrading PB Apps overview (described in the second link) contains helpful information for upgrading from each release of PB since PB 6.5. You should carefully read through each section beginning at PB 9 and work your way up through all of the sections to the most recent release.

What it boils down to is this: You need to perform the due diligence to try and determine what it will take to upgrade your PB 9 application - nobody knows your application better than you. Any advice you get here is going to be of a general nature. Armeen is correct... the migration should go relatively easy, but realize there are no guarantees that this will indeed be the case in your situation.

Good luck!
