Looking for a bit of advice from the community on what seems to be an unusual situation from my searches for a guide - updating an on-prem SP2013 farm from the 2010 to 2013 workflow engine.
Background: we got the farm handed over for support from another company, who built it as SP2013 Standard but for some reason didn't install the 2013 workflow engine.
All I've been able to find on doing the update to 2013 WF is for an SP2010 farm being updated to 2013 in full, or enabling it from a scratch-built 2013 farm.
Can anyone point me in the right direction for this one? Not even done a farm build before so a bit wary and making sure I plan correctly as we have no staging farm to test it on first!
