Firmware Update

I’d like to update to the latest firmware.

When I verify the SyncStation it says
Hardware Version 24
Software Version 00.04 26/10/09

The new Firmware says
Hardware Version 26
Software Version 00.04 17/01/14

Can I use this firmware update or do I need to use a firmware which is compatible with my hardware version 24?
Which firmware update would be the right one for me?
