why do u need to upgrade to 9.4.8 before going to 10.2.1?

 

 

1b, if network failover is disabled, both unit will go active. i think u should disconnect all network connectivity.

1f, image2disk --format=volumes BIGIP-10.2.1.297.0.iso

 

sol12561: Change in Behavior: The image2disk utility --instslot and --format options are now mutually exclusive

there are some change behavior in v10.x. these are what u should take note.

 

sol9947: Change in Behavior: The Peer Management Address setting is required for BIG-IP version 10.x systems configured for network failover

finally, if there is any issue in loading config after upgrading, try b load and it should show what is wrong.
