Neal's case is just the fact that defects get fixed in multiple ES, so you have to be careful to verify that the version you are upgrading TO also has the fix for the bug that got you onto the ES to begin with. From 7.1.5 to 10.5 you'll be fine since the last ES for 7.1.5 was long before 10.5 came out.
In general you should be fine going from the 7.1ES to 10.x. You're going to be rebuilding anyway for the P2V migration. -Ryan On Sep 5, 2014, at 10:33 AM, Haas, Neal <[email protected]<mailto:[email protected]>> wrote: It’s been awhile, but we had an ES 7.1.5….. This ES was for a Raid driver issues with the MCS. We upgraded to 8.X (don’t remember the exact ver.) but the UPGRADE reverted back to the Raid driver issue. We ended up rebuilding with a fresh install to each of the subs – then did the pub. Check with TAC I believe they will tell you with an ES upgrade you should DR.

So it appears this customer has an Engineering Special for Callmanager 7.1.5-12009-1 that isn’t listed on the Compatibility matrix (ESs never are). Can they direct upgrade to 10.5.1 or do I need to upgrade them to 7.1(5b) first then 10.5.1?
