In this blog post, we’ve covered the 8 step migration process using Zero Downtime Migration from On-Premise to the database on the cloud.

8 Step To Install & Configure ZDM In Oracle Cloud

1) First, step is the download ZDM script and configure the script on the machine. ZDM supports the Linux 7 or later version.

2) The second step is to connect the ZDM with the source database and target database using SSH key file. After running the ZDM command insure that you can perform the dry run/test migration operation before the actual migration process.

3) The third step is to establish connectivity between the On-Premise database and object storage so you can transfer the source files onto the storage on the cloud and then transfer the files on the target database.

Note: For Exadata cloud at customer you can use local NFS based storage or zero data loss recovery appliance instead of on Object storage.

4) The fourth step is to transfer all the backup files i.e Full backup and incremental Archive from the source/primary database to the object storage.

5) The fifth step is when all the necessary files copied over, now instantiates standby using these backup files on the target, ZDM orchestrates everything it will talk to the object storage.

6) The sixth step is ZDM sets up Oracle Net Services connectivity between the source and target database and completes setting up the Data Guard configuration such that the source/primary database. after this ZDM will verify that the Standby Database is fully in sync with the Primary Database.

7) The next step is, ZDM will perform data guard switch over and change the role of the primary databases to standby database and vice-versa.

Note: Automatic application switchover can be ensured with the proper configuration in ZDM.

8) ZDM finalizes the migration process, terminates Data Guard connectivity between the source and the target The user can request ZDM to pause before Migration, also controlling when Data Guard synchronization between the primary and the standby will complete.
