Can MX250 failover to MX100?

[GFrazier]

Got a situation:

Client site originally had a MX100.  They setup a secondary location with a MX250.  They are consolidating back to the original location and want to use both firewalls for redundancy.  I want to use the MX250 as the primary.  Can the MX250 failover to a MX100?

That would not be possible:

The secondary MX must be the same MX model as the primary. Warm spare functionality is not supported between different MX models (e.g. MX80 & MX100).

Thanks Bill.  Looks like they will just have to get another MX250 for redundancy.
