To install or upgrade DevTest 8, 9 or 10 a valid license file (devtestlic.xml) is required.
DevTest 8 is installed and is currently running. For an upgrade to DevTest 9 or 10 is there a need for a new license file?
The license file shows a tag with only version 8:
The license file that is used for DevTest 8 can also be used for a later release like DevTest 9 and 10.
This is even though the versions tag in the license file (devtestlic.xml) may only show version 8:
So the same devtestlic.xml file can be used for 9 and 10 also.
Check that the <validuntil> tag does not show a date that is in the past.
If that is the case, a new license file needs to be requested from the CA customer care team
