Database migration from 12c to 19c with OGG 19c

in GoldenGate, Streams and Distributed Database (MOSC) 1 commentAnswered

To make it clear:

Current live environment windows server 2012 R2:

S1 - Source database 12c on machine MS1

T1 - Target database 12c on machine MT1

SCM1 - Schema name of data on S1 and T1

OGG 12c configured as live reporting from S1 to T1.


Migration environment windows server 2019:

S2 - Source database 19c on machine MS2

T2 - Target database 19c on machine MT2

SCM2 - Schema name of data on S2 and T2

OGG 19c configured as live reporting from S2 to T2.


The plan is to migrate S1 to S2, database 12c to database 19c.

To reduce downtime, we will replicate data from S1 to S2 by installing OGG 19c on S1 in addition to the current OGG 12c.

Howdy, Stranger!
