Looking for upgrading Nexus 9K  redundant VPC bundle.

Current os

Can someone share simple procedure for ISSU ?

Steps :

1. read the release notes. and understand the caveats.

2. back up the config out of the box.

3. follow the link above and upgrade steps available in detailes.

4. check all the links are dual homed, if any oraphan ports they expected to go down (so for that required down time or maintenance window)

5. is this only vPC or any FEX connected ?

Thanks for reply,

There is no Fex only vPC.

 that process should works, as long as the end device dual-homed.
