Yes to performance degradation related to disk firmware. Shelf firmware is not just performance impactful but disruptive as this process will take whole shelves offline while it upgrades the controller firmware. Figure 2-3 minutes per controller (Multiplied times # of controllers) If I remember the last time I did this.
Also there will definitely be a I2P (inode to parent) initialization, which depending on how much data you have can take long time. See page 32 of the upgrade guide for more information
http://now.netapp.com/knowledge/docs/ontap/rel723/pdfs/ontap/upgrade.pdf
The aggr/vols going through this initialization will be online but again it will cause some performance degradation. I believe the upgrade doc includes this information but you can monitor the status by the following commands:
priv set advanced wafl scan status

How many disks? I'm assuming FC disk.
Make sure you don't update your disk firmware before upgrading Data ONTAP. The now site mentions bug ID - 113823, so do some reading on that. Also expect some temporary performance degradation when you do the disk/shelf firmware upgrade (this is not the same as upgrading Dataontap. Disks, and shelves all have their own firmware revisions you need to look out for). The disk upgrade itself can take 2-3 min per disk drive.
You're going to love the improvements from a 6->7 upgrade though. Auto delete snapshots, and flexvols = your friend.
As long as you have NetApp involved you should be covered.
Good luck!

We are planning to upgrade our clustered 940 filers from 6.5.6P3 to 7.2.3.
We had netapp run an Upgrade Advisor for us.
I would appreciate any comments/suggestions on upgrading to 7. We are running 7 on a couple of 3050's that were shipped with 7, but we haven't upgraded any systems from 6 to 7. Any gotcha's that anyone is aware of?
We only use these systems for CIFS and NFS.
Thanks,
Jeff.
