Re: Rolling Cisco Switch Upgrade

i don't see why not, if multipathing software is licensed and properly configured, hosts are dual attached ..should be no issues. When you you upgrade MDS you never lose fiber connectivity but having  working multipathing never hurts. Just run the proposed config through E-Lab to make sure PowerPath, navi agent, Flare code on Clariion are all happy with 5.01 on MDSs.
