We are about to upgrade the Nintex 2010 Workflow version on each farm (Prod, Test, Dev). We have development occurring on the Dev environment continuously. The plan to upgrade the farms is to start with the development farm, run some tests on the workflows and come up with a strategy to upgrade the test and prod farms based on the results from the tests.
During the validation time period in development (which now has the upgraded version), development on new workflows will continue to occur.
Will we need to cease promoting workflows through the environments until the upgrade process has been executed on the remaining two farms? If we were to promote workflows to the test and prod farms I assume we would encounter issues, what would be their cause and is there a possibility of mitigating these?
e.g. I create a workflow with a flexitask in the upgraded farm. I specify a BCC recipient. Will this workflow be able to be promoted to a farm running a previous version which does not have the BCC functionality for Flexitasks?
