I want to upgrade Manager but I am using a very old version Manager_v16.10.56.
Do I need to upgrade in stages? ie. v17 then v18 etc.?
I tried to upgrade to latest Manager_v21.4.60 but I cannot load any of my databases.
Any help much appreciated.
Because you have tried to open your file(s) with a newer version, you may be forced to add an older backup first. The backup will be converted. So add the backup first, then install v20.9.89 and open the backup, then install the latest version. You may or may not be able to open your current live database, depending on what else you might have done to try to get things running.
