Stacking Catalyst 9300

[mikeok]

Hello!

I have a stack of 3 Catalyst 9300 switches and have to connect 2 other to the stack.

Output "sh version" from the stack shows

Cisco IOS XE Software, Version 16.12.02
Cisco IOS Software [Gibraltar], Catalyst L3 Switch Software (CAT9K_IOSXE), Version 16.12.02, RELEASE SOFTWARE (fc1)

And both new switches have version

Cisco IOS XE Software, Version 16.12.02
Cisco IOS Software [Gibraltar], Catalyst L3 Switch Software (CAT9K_IOSXE), Version 16.12.02, RELEASE SOFTWARE (fc2)

Will this difference in releases [fc1 vs fc2] prevent to stack the new switches or not? Should they be the same of it is enough to have the same major version 16.12.02?

Thanks!

 - Probably not an issue when adding to a stack , in  the below thread the answer of andrew b explains the difference between fc1 and fc2.
