Hi Vinod;
Unfortunately, you can not migrate the "Appeon_workarounds" PBL as this code was only for PS2020 that supported both the Appeon Web and Appeon Mobile feature applications running under IWA or AWS installed on the target machine.
PS2020 was fully deprecated after the PB 2019 R3 (see link below) and thus, all the Web & Mobile features. The new PS2022 is based on a totally different architecture & technology stack (Cloud Native). So you would need to refactor your PB2019Rx / PS2020 applications to be totally Client/Server based. Then PB2022 & PS2022 will automatically convert them to N-Tier "Cloud" Apps from there. FYI: https://www.appeon.com/products/powerserver-tour
In the mean time, if you need to support Mobile & Web apps - then I would highly recommend that you stay on PB2019 R3 with PS2020. Those are "long term support" (LTS) product versions and will be supported until 2026.01.22. So that would give you some time to switch over technology stacks before your current Web/Mobile App implementations are EOS/EOL.
Starting in PS 2021 ... FYI: https://www.appeon.com/developers/discontinued-features-in-powerserver-2021
