gets me every time too. The reasons I've found it can be different is if
- some licenses are listed in different line items due to orriginal purchase data being different (and possible purchased at different version)
- when they may have been upgraded from Workstation/ArcView/ArcGIS, etc.
- if they are on maintenance
- ??
If you have more 10.0 than 10.1+, it may be that you didn't have all on maintenance and/or didn't convert all to "whatever". To me the provision/authorization/licenses seems a bit circular, and it's easy to get confused as you circle back.
Since I've been the main license administrator for 30+ years and have seen all the upgrades (from the Data General mainframe, on), I have deep knowledge and have kept my own notes over the years...and provided all the paperwork at one point to make sure all was accounted for. I'm now trying to educate others here on all the ins-and-outs of the licensing system, including the changes that are coming. It's an art form, for sure. But that is just me blabbing on.
My point is, just looking at the MyEsri site does not always provide clear answers. If you have a papertrail, have been dealing with it all transactions yourself, and/or has a long term customer service rep that knows your account very well, that helps. Best thing I ever did was take the 6-mos+ it took to get ours all figured out (back in early AV to Desktop days). From that point forward, much easier to do transactions. But in most cases/orgs, my guess is that isn't the case. In that light, I can see why they are pushing named-users and annual subscriptions (vs concurrent). It would be easier to maintain...you pay, or you don't get. Not that I like that one bit, but it may be easier in the long run.
If your local rep doesn't know, and you have the time, you might be able to track things down with someone in Redlands.. And it might be worth it if the 10.0 number is > than 10.1+. We still have 9.x and even 3.x that were never updated....still legal to use I guess (and for updating things, nice to have access).
re: disks....legally, if local rep doesn't have it, probably need to contact Redlands. (or you might be able to find if you have a local agency that still has a copy..The install disks don't really do you any good without a valid license anyway. ...still would check with your rep).
