I have been waiting in an Adobe Support chat for 1:10 while he researches an answer to this question.
I just moved to a new iMac with Catalina. I did do the update for LR Classic CC, but did not open it because I knew that I have not yet upgraded/updated my catelog that is on my old computer running High Sierra. I noticed on the Support website that it is not recommended to open a catelog that is still release 7.5.
So what do I do? If I upgrade the catelog while it is still on the old computer, will I be able to then open it on Catalina? Would it run without problems? Should I not put Lightroom on the new computer?
I did move the current catelog to the new computer. If I click on it to open it will it launch the LR app and convert it to the new catelog update? Should I open the update and try to import it or open the catelog?
It is now 1:25 minutes. Do you think the support person is still there?
