Thanks Donnie (you seem to be double-posting everything though you probably know that?).
We have an issue where we recently upgraded from standard to Enterprise CLA, but only just got around to upgrading from 8.0 to 9.0 so only just got to use the key.
Under 8.0 we were evaluating the VSA and D2D with Dedupe, so had an eval license for those features.
Under 9.0 when trying to apply the full CLA license that Commvault sent us it won't have it, it just complains that the new license doesn't contain any evaluation for dedupe (which I didn't expect it to since Enterprise CLA comes with dedupe).
When I look at the license file it seems that all the "duplication" features are set to "0" and there's no reference to Enterprise CLA SKU's in it, only Core CLA SKU's.
It's going back and forth between our reseller and Commvault, you can probably read between the lines on that comment, but to me it just looks like a wrong license file - though I don't know exactly what it should say.
