Mixed Config: VTI and classic ipsec

Is there an issue with running these together on the same router?

I'm just trying to get a migration plan together to move to VTI.

Re: Mixed Config: VTI and classic ipsec

Cisco IPSec VTIs are a new tool that customers can use to configure IPSec-based VPNs between site-to-site devices. IPSec VTI tunnels provide a designated pathway across a shared WAN and encapsulate traffic with new packet headers, which helps to ensure delivery to specific destinations. The network is private because traffic can enter a tunnel only at an endpoint. In addition, IPSec provides true confidentiality (as does encryption) and can carry encrypted traffic.
