upgrade.sh v4.6.9:
* Fixed issue where where patch-only upgrades of instances after the first
in a multi-instance environment are skipped.
* Corrected error message for scenario where downgrades are attempted; the
logic was correct but error message was confusing.
verify_sdp.sh v5.17.3:
* Extended '-skip version' meaning to also skip new live binary version
comparison checks.
Related updates:
* A call to verify_sdp.sh in the switch_db_files() function in backup_functions.sh
now skips the version check.
* A call to daily_checkpoint.sh now skips the version check.
