Now that DevTest 8.0.1 is GA (see @Stefana's post from earlier today), how about upgrading to this latest version that includes fixes to reported defects as well as some product enhancements?
See here for a PDF that takes you through the changes in licensing, the importance of Enterprise Dashboard and then migration your existing version (Lisa 6 and above) to DevTest 8.0.1.
Some important topics covered in the doc -
- Name change
- Understand the key points prior to migration
- Pre-Installation checklist (includes backing up your data)
- Post-Installation Tasks
- Remote components configuration
- Verifying Installation
