Stack Configuration change question.

I have a stacking question.  I have 5 new 9300 switches that will be replacing existing switches.  In order to limit disruption we are looking at replacing the switches 1 at a time.  I have manually given priority 15 to switch 1.  It sounds like we need to install them in reverse order so install switch #5 then #4 etc.  I will need to make configuration changes as we install them.  What possible issues will I run into making configuration changes with primary switch added back last.  I think it will be fine but covering all my bases.

 

 

Stack#sh switch

Switch/Stack Mac Address : 0c75.bd34.5580 - Local Mac Address

Mac persistency wait time: Indefinite
H/W Current
Switch# Role Mac Address Priority Version State

Re: Stack Configuration change question.

This should work fine. I would also give a priority (not default 1) to the other switches.

Example:

*1 Active 0c75.bd34.5580 15 Ready
2 Member c4c6.03b5.4200 10 Ready
3 Standby 0c75.bd34.6b00 8 Ready
4 Member c064.e418.fd00 6 Ready
5 Member 0c75.bd34.5280 4 Ready

This way you know for sure, when switch 1 goes  down switch 2 will take over and if 2 goes down, 3 will take over and so on...

Just remember not all configs are the same between older switches and the 9300. So, copy from the old switch into notepad, make changes and paste into the 9300.
