UAT for 2021.4 in Server --- delay before PROD is updated

[aehrenwo]

What is the best solution if I need to test if there are any issues with our group's workflows in our DEV/QA environment? Recently upgraded to 2021.4. but our PROD environment won't be upgraded until early March (it is 2020.2) 

It appears it is not possible to have 2020.2 and 2021.4 installed at the same time. 

Do I need to wipe out 2021.4 and reinstall 2020.2 in order to continue publishing to PROD?  And then vice versa if I need to go back and do testing? Seems like a lot of time that will be wasted. 

Any suggestions?!!!

Hi @aehrenwo - You can have two versions of Designer on one computer if one of them is admin and the other is non-admin. However, you will need two valid licenses then.
