Version mismatch issue in stack

[osman869]

Hi 

I have stack of 5 switches 4 are C9300 NM 2Q 24ports and 1 C9300 NM 2Q 48 Port

All the version are 

1 Standby 6c03.097d.5a80 1 V05 Ready
2 Member f87a.41be.ca00 1 V05 Ready
3 Member f8a7.3af7.4600 1 V05 V-Mismatch (its same model but 48 P)
*4 Active 44b6.bea8.db00 1 V05 Ready
5 Member 6c03.0991.1a80 1 V05 Ready

I have manually downgraded the switch to match the version of others but still its showing the mismatch.

Cisco IOS XE Software, Version 16.12.04 is same on all switches, is there anything else to check.

Hi Kasum,

Thank you for reply

I did reboot but still the same.

I can see that CISCO IOS XE Software is 16012.04 Fc5 is same but the difference in 48 Port switch is BOOTLDR, system bootstrap is version 17.3.2r while in other four it is 17.3.1r

does it make any difference?

In enable mode, enter the command "install autoupgarde".

Thanks, guys!

The 48 Port switch was in bundle mode so I changed to install mode and it came to the stack.

A stack of 5 9300 and on 16.12.4. 

Very brave.
