Yes easy... and so simple if/once you know it
It seems a couple of my issues after the cPanel upgrade had to do with possible mix-up of files on my computer, and what I downloaded from the old server and then uploaded to cPanel.
i.e. the old server download had lower case settings.php, yet my computer files which I would have used to initially upload to that server had uppercase Settings.php
I will try to remember to recheck or compare original files next time.
So now on to the MySQL DB changeover to cPanel.
It has been a good exercise overall as it makes me look at all the older scripts and see which ones are no longer working properly. I appreciate your help and guidance Ken, and GoDaddy was overall very helpful to my many support questions. And the cPanel hosting upgrade cost for 2 years is the same cost as a one year renewal of my old hosting so a good bonus, for my temporary frustrations!
