IKEv1 and IKEv2 on the same router concurrently

[salomidhogela]

Hi All,

I have multiple customers connecting via ipsec tunnel on IKEv1 and I would like to upgrade one customer to IKEv2 without interrupting the rest. Is it possible to run both version on the same router? Do I use the same crypto map applied on the interace?

Sure you can 

Crypto map MHM seq 10 ....<<- for IKEv1

Crypto map MHM seq 20.....<<- for IKEv2

The seq must be different.
interface x/x
crypto map MHM

How do I apply it on the interface? I do not have an option for the above, additionally can I use the same transform set?

!

Router1(config-if)#crypto map salom ?
redundancy enable redundancy

Router1(config-if)#crypto map salom

check above 
there are two crypto map 
one in global and other under interface 
we use one crypto map name under interface 
in global we assign different seq for each crypto map (same name)
hope this clear 
thanks
