I'm upgrading to SP4. Should I back up my SP3 database?

During the installation of the Sticky Password 4, all of the data from your existing database will automatically be imported into Sticky Password 4. Because of the newly designed database used in Sticky Password 4, a migration to earlier versions of Sticky Password is not supported. For this reason, we recommended that you save a copy of your current password database, just in case you decide for any reason to reinstall your previous version of Sticky Password.

To make a copy of your database:

Copy the default.pws file, which can be found in the My documents/Sticky Passwords folder, and save it in another location (folder) on your computer. If you wish to save it in the same folder, it will be necessary to change the name of the file (e.g. oldpassworddatabase.pws).
