This is a MAINTENANCE Release (as opposed to a Release Update) - it can ONLY be applied on top of NetBackup 7.1. (If you are running 7.0 or 7.0.1, you will need to upgrade to 7.1 before you can apply 126.96.36.199.)
Please note that maintenance releases are CUMULATIVE - that means that 188.8.131.52 contains all product fixes included in 184.108.40.206, 220.127.116.11 AND 18.104.22.168. If you are currently running NetBackup 7.1, you may apply the 22.214.171.124 maintenanace release without installing 126.96.36.199 or 188.8.131.52. In fact, if you are still running NetBackup 7.1, we would HIGHLY encourage applying 184.108.40.206!
To check to see if your particular Etrack is resolved in NetBackup 220.127.116.11, please refer to these Release Notes:
