Nexus 6004 upgrade nightmare

I have now had 2 weekends ruined by a botched ISSU upgrade on 2 pairs of nexus 6004.  We are going from 6.0.2.N2.2 to 7.0.5.N!.1 and each time I encountered a bug.  Last week it was an igmp snooping bug.  Turn off igmp snooping and it will be fine.  So this week I did that and no, it wasnt fine.  I hit a new bug regarding sending BPDUs down dual sided VPCs (ouch).  Thank you very much.  Has anyone else had these kinds of problems with ISSU upgrades?  Im have done 15 pairs of 5ks in the last 2 months...the 6004s are going to send me to my grave....Ironically, its a fast root cause analysis - but it seems there is no non disruptive upgrade to 7.x
