We are looking at upgrading our 9513s from v3.2.2c to 4.1.3a. The upgrade procedures in the docs look quite straightforward. Has anyone experienced any issues/glitches during the upgrade ?
Yes, I believe it is. The way i approached it was:
1.Did the 3.3x upgrade
2.did the 4.1x upgrade
3.powered off the switch and added the new fabric-2 modules, and any 8gb modules (this can be skipped if you are not needing 8gb module support)
4.powered on the switch (this can be skipped if you are not needing 8gb module support)
5.upgraded fabric manager to 3.3x, never launched it.
6.upgraded fabric manager to 4.1x, logged in to verify everything worked.
this worked flawlessly for each 9513 i upgraded.
