Time Length

This whole process is expected to take 6-24 hours.

Some systems could be impacted for days, if issues are encountered.

Systems Impacted

This change impacts both hetzner2 and hetzner3. It's possible that we'll need to restart one or both of these servers during this migration, which could affect the availability of all OSE & OBI websites.
