I have several servers connected to 4100 and 4900 switches that run on different speeds which is 1GB, 2GB and 4Gb. These switches currently run on firmware v5.1.0a.
I am planning to upgrade these switches to latest v6.3.1a firmware. After the upgrade would it continue to support these servers that are running on 1GB, 2GB and 4Gb speed or do I need to upgrade the server HBA speed before the firmware upgrade.

It should work fine if the drivers are still compatible with the new FOS. Its not just the speed remember.
I checked the release notes and the cli guide and 1 Gbps is possible. portcfgspeed for 6.3.1 shows the 1 gbps option, thats my basis for the answer.
