Hi Inquiring
As far as I have seen on here, you can upgrade to the new version but you will need to step upgrade as it only seems to upgrade from v19 successfully. The software downloads are here:

Please look through the Community Forum as there are a lot of problems/bugs and it is very slow (especially as the file becomes larger) and can be sensitive (crash). There are on-line options for bank feeds, STP, etc. that many find useful. I tell the few clients who are on the new version to make regular backups, even if they are on-line as there can be some occasions when you will need to restore.
If you do want to go ahead, then make sure your file is as small as possible by optimising and purging because size really does make a difference to speed and the new version doesn't have a purge function. If your file becomes so large that it is unmanageable on a day to day basis, then you will be advised to start a new file (usually on 1/7), although there is a 3rd party provider that can purge but I cannot name them on here.
Cheers
