During an upgrade, Site Recovery Manager does not retain any advanced settings that you configured in the previous installation. This is by design. Due to changes in default values or improvements in performance, advanced settings that you set in a previous version of Site Recovery Manager might not be required by or compatible with the new version.
During an upgrade, Site Recovery Manager preserves only protection groups and recovery plans that are in a valid state. Site Recovery Manager discards protection groups or recovery plans that are in an invalid state.
