the internal storage for profiles will be automatically migrated. it is a one-way one-time transition. if you run Secure Shell on multiple systems, make sure they all upgrade to the latest otherwise the connections won't show properly. Chrome often won't auto-upgrade extensions if you have a window open, so you might have to close them all first.
