Hi Karl, 1. Those servers won't be able to re-register with Scalr. This is something we plan to change later this year, but we aren't there yet. In the meantime, we recommend setting up replication in addition to snapshots (this will be possibe using the installer in 5.3, which we expect to release shortly, though until then you can of course do it manually).
2. You'd need to change the user data for those instances. This is obviously an intrusive process, so we very strongly recommend you use a domain name instead of an IP for the Scalr endpoint.
