We have a client that's interested in migrating their system from a local server to FileMaker Cloud using BYO. They have an existing VLA. Ideally we'd like to transition them over the course of a week or two so we can troubleshoot WAN access speeds, etc. The question is this: during the transition will the process of setting up AWS using their existing license disable access on their local server? We're not trying to circumvent licensing restrictions, but don't want to permanently kill off access to their existing server until we've finished troubleshooting.
Thoughts and/or alternative approaches?
