We are in process of upgrading on prem nintex 2013 forms and wf from older version to newer version. Is it recommended to take prod backup before updating to newer version?
if you speak of patching a Nintex 2013 Version to the newest Nintex 2013 Version you don't necessarily need to make backups of the production environment. If you feel better this way you can surely do but in 8 years of patching Nintex installations there was not even one time I needed to roll back the farm by using a backup created before.
Hope this helps.
