Thank you all for that very detailed and entertaining answer!  As you will see, I've posted a new question which obviously relates to the last question I asked.  I know this because it sent me to my last question and said the answers to it were the RECOMMENDED answers for the current question!  So, I figured it might help if I posted the question to IRonMan, itonewbie and Ernie, since I'm sure you can all answer this one for me as well!

HERE IT IS:

I had ProConnectOnline in 2017, then ProSeries in 2018, have decided I'd prefer to use ProConnect again in 2019. How do I convert my 2018 info or do I need to?
All my 2017 clients are showing up in the 2019 listing for creating new returns for but I'm just thinking it would be easier for me if the info in Proseries (2018) were converted to ProConnect Online because the skipping of the 2018 year will inevitably leave out major changes in business client reporting such as depreciation or sales of rental real estate, etc...

JUST REALIZED itonewbie has already given me an answer before I even posted this question to the 3 of you!  So, itonewbie, Thank you for being the champion you claim to be!
