Converting your version 7.x database to a version 9.x database is a two step process. First, you have to convert your version 7.x database to a version 8.x database. Then you can run version 9.x which will convert your version 8.x database to a version 9.x database. Here's how:
 
STEP 1. Launch SOHO Notes 7.x or SOHO Organizer 7.x and make sure you can see all of your information then quit the software.
 
STEP 2. Install and launch SOHO Notes 8.x or SOHO Organizer 8.x. You can download from here:

When you run version 8.x, you may be asked for a license key but you can ignore and just run as a 30 day trial since you won't actually be using version 8 beyond that time frame.
 
Upon launching the software, you'll be asked if you want to convert your version 7.x data to the version 8 format. If you don't see this message choose File > Migrate From Version 7 and then follow the onscreen steps. Once the conversion is complete, quit the software.
 
STEP 3. Install and launch SOHO Notes 9.x or SOHO Organizer 9.x. A window will appear to help you convert your version 8 database to the version 9 format. Follow the on-screen prompts.
