Active/Standby Trunk Port Migration

I need to migrate the internal based trunks on the Ha pair from 1Gbe copper to 10Gbe fiber and had a few questions.

Does the physical network connections have to be the same on both cluster members? The reason why I am asking is I currently have an active/standby clusters with the inside vlan consisting of a (4) 1GBE copper ports on both the active and the standby. I need to migrate off the (4) member 1Gbe copper based trunk to a (2) member 10Gbe fiber port trunk. My plan was to perform the migration on the standby unit first and then fail from the active to the standby and do the same thing on the previously active node which will be in standby after the forced failure.

I was just curious if the active is still using the 1Gbe based trunks and the standby using 10Gbe trunks, if it will cause a problem when performing the fail over. Trying to migrate the trunks with minimal impact to the traffic, since the boxes are in production and can't be taken out to perform the migration.

Any feedback or experiences on the topic would be greatly appreciated.
