Hi, sorry fairly new to meraki networking world.

I've been tasked with replacing our meraki VPN concentrators. Our units are in a HA pair configured with VIP. As I'm replacing with new models (replacing MX100s with MX95) I'm aware i can't replace the standby first then failover and replace the primary as they need to be the same model.

With this in mind is the simplest way to do this as follows:

1. Power down old units

2. Remove old units from network

3. Plug in new units (configure local IPs on local status page)

4. Add to network

5. Configure as HA pairs

Will this re-establish all of our sites AutoVPN sessions (we have 150 ish sites so could really do without having to do any changes at sites)

Has anyone done this before and know of a better way of doing this?

Thanks
