If you have any other database server  installations (e.g. 10.2.0.5, 11.2.0.2), you should upgrade such databases if  you would like the older databases to continue using database links with  newer versions of databases.         What is the change introduced by the patches listed  above?    The patches listed above make the older databases  capable of supporting increased SCN soft limit (i.e. support transactions  with higher SCN rate) though the increased SCN soft limit only becomes  effective at a later time (after April 2019).       Timelines    All databases should be at the above mentioned  release/patchset/ PSU/BP levels (or above) before April 2019.       Support and Questions    If you have any queries please post them in the  Database community page: https://community.oracle.com/message/14710245#14710245
