When doing a fresh installation of 20.2.7 and using a dbsavefile.SSdb to migrate your database, the Spectrum installation fails and the log indicates that dbmigrate hit a Segmentation Fault and does not migrate the database.
Release : 20.2.7
Engineering is aware of this issue and will be fixing the issue in a future release.
To workaround this you must install 20.2.5 first, and then upgrade to 20.2.7. The reason is that when the 20.2.5 install is there, the 20.2.7 install will not overwrite the dbmigrate executable.
