We are planning to Migrate from PAYG Subscription to CSP Subscription, Currently the Express route is configured in PAYG Subscription, as the Express Route cannot be migrated is there a way we can use the same keys, IP ranges, while we are connecting the new express route in CSP Subscription.

Azure ExpressRoute
Azure ExpressRoute

    The link provided dosent answer my query. The question asked is on the use of existing Express route keys on the new express route for the CSP subscription.

    @Kamal Dhingra

    The overlapping IP ranges would result in an overlap on-premises for the routes used to establish BGP sessions so this may not be a good idea to use the same IP ranges in the new subscription.
