currently have a ISR4351 that is using traditional licensing. The box currently has ipbase,advanced, and sec licensing installed. However I have recently found that because the router does not have HSEC we are limited to 85mbps for our vpns, which is throttling traffic for one of our branch sites, so the plan is to GET HSEC applied to the device to resolve this issue. We currently have an ISR4351 HSEC license available in our Smartnet account. Would I be able to convert this device that is currently using traditional licensing to smart licensing to add HSEC , but still retain my licensing already installed in the box? Or is their perhaps a better route I should be taking to complete this? I am a noob when it comes cisco licensing so let me know if further details/clarification is needed. Thanks.
