I had an upgrade on PowerChurch Plus 10 over the Internet in August 2011. I only have the disc for version 10. If I download it on my laptop then take backup from my desktop will it convert properly when I install it on my laptop?
I've checked the official website and it doesn't mention about the problems with the backup and importing procedure, therefore you should proceed as you mentioned above. Secondly, there is a new version of the software released on the official website. There is version 11.5 available for downloading through the link below. There have been 5 years since the update and many things changed in the software, therefore it's recommended to have an updated version.
