Are there any other documents that describe the 19.1 and 22.1 spec changes in Pega Robotic Automation?
Also, I would like to know all the things that will change in Automation if I migrate from Pega Robotic Automation 19.1 to 22.1 with the migration tool.
@ReiA7543 22.1 offers an entirely new development environment for Robotic automations. It is no longer based on Visual Studio 2015 and is instead its own IDE. In terms of what will change for your automations; functionally, nothing. They should still run as expected and have a similar look and feel to them. Practically speaking, the biggest change in terms of running will be the loading times of an automation. It is much more efficient in 22.1, so projects will start quicker. The main difference architecturally is the merging of projects in 22.1. 22.1 projects change what reusability is by using Assets instead of separate projects (as of the current versions of 22.1 at the time of this posting). At the end of the day though, if you upgrade your 19.1 solution to 22.1, it should run as it has before.
@ReiA7543 Also, you can install both 19.1 Studio and 22.1 Studio on the same machine. Go ahead and upgrade your solutions and begin testing to see if there are any areas you have questions or concerns with.
