I am planning on replacing an amount of WS-C2960S-48FPS-L switches in out environment. My basic plan is as follows;
1. Upgrade new switches to latest recommended software
2. Install stack modules where appropriate
3. tftp the config of the existing switch(es)
4. tftp the config to the replacement switch(es)
5. physically swap old/new (paying attention to VLAN/significant connections)
Questions;
1, Does this sound like a good approach?
2. How best to handle instances where switches are stacked? Do I need to tftp the image to each switch in stack or just the first (ie will stacked switches adopt the config from the first)?
3. In instance of stacked switch upgrade do I need to replace all switches in the stack at the same time (to ensure hardware/software compatibility)?
This is the first time I have had to go through this process so your expert advice would be appreciated.
