DataPower Version Upgrade from 4.0.2 to 5.0.0

Yesterday, I had the opportunity to upgrade a DataPower XB62 appliance from version 4.0.2 to version 5. I followed the steps specified in the product documentation and simplified it:

1. Download the images in Fix Central

2. ENSURE that you have  a working privileged user ("admin") and that you have access to it (meaning the password you're using is recent)

3. Login as admin in default domain

4. Backup the appliance's configuration
1. Export Configuration
2. Select Create a backup of the entire system 

5. Backup files from local:/// on all domains
1. Login to application domain
2. Export configuration
3. Check "Export all local files" option
4. Download
5. Repeat step 3.a for other domains
6. Delete all files in local:///  on all domains to free up space (do this if there's little space left in your appliance)
7. Save Configuration

6. Disable application domains
1. Configuration > Application Domain
2. Disable domains other than the default domain
3. Save configuration

7. Reboot to free up resources
1. System Control
2. Set mode to Reboot System
3. Click shutdown button

4. Wait for reboot

8. Upload the firmware image
1. System Control
2. Boot Image > Upload or Fetch

9. Verify  the firmware upgrade version

10. Enable Application Domains and Restore the local:/// files you backed up if there were any.

Well, that's about it. This is just a short version of the procedure I recommend that you still checkout the product documentation.
