Am looking for best way to manage the migration of a client from ADSL to a Leased Line with minimal impact to Email Delivery
They currently have an ADSL line which is not sufficient and want to upgrade to a leased line - the problem being that when they upgrade the MX records will have to be updated and they take 24-72 hours to resolve.
What is the best workaround for this
One solution we were thinking of was to install another NIC card and separate routers and firewalls (temporarily) for both connections until the Migration is complete - is this feasible? the best solution?
Looking forward to hearing your ideas to my first question since becoming a premium member
