Robotic 22.1 upgrade challenges

Im trying to upgrade a 22.1.46 robot solution to 22.1.48

When attempting to open the 22.1.46 .pegaProject file in the 22.1.48 studio a pop up appears stating “… the solution must be upgraded first … do you wish to continue?” If yes is clicked no further activity takes place

The 22.1 studio’s all have 19.1 upgrade features where 19.1 solutions are easily upgraded so upgrading from 19.1 to 22.1.x is reasoably straightforward

Additonally in visual studio with the 19.1 plug in’s upgrading solutions was simply a matter of opening an earlier 19.1 solution in the higher 19.1 visual studio environment

However it is not clear how to upgrade between 22.1 solutions as stated above

Please advise

@RichardB3397This dialog will appear when you open a solution in a later version of Pega Robot Studio than the one used to create the solution. It is really just a warning that opening it in the latest version will upgrade the files and that you will no longer be able to open it in lower versions. There is no specific process other than opening the solution in a later version to actually perform an upgrade between build versions of the same major/minor version. To go from 22.1.46 to 22.1.49, you simply need to open the solution in 22.1.49 similar to how you did between 19.1 versions.
