License files used with Rational Common Licensing 7.1.x and earlier or Rational License Server TL 2.0 must be migrated to the Rational Common Licensing 8.1. required format. The format requires the vendor line to be "VENDOR ibmratl". You can use the License Migration Utility to migrate the license files. The utility is included with Rational Common Licensing 8.1.
To migrate license files:
The migration utility creates a backup of the license file in the same directory as the license file. The extension for the backup license file is .bak. You can use the license file with Rational Common Licensing 8.1 after the license file has been migrated.
