Hello, I have to upgrade a 6509 with SUP720. There is a WS-X6724-SFP card on it. I would like to install the 12.2(33) and require a ROMMON upgrade on the 6724 card. Today is installed on SUP720 the 12.2(17d)SXB version. If I upgrade first the IOS will I be able to upgrade the ROMMON of the 6724 later (due to requirements) ? Is better to upgrade the 6724 ROMMON before (can be that new ROMMON is not compatible with old IOS) ?
