Move to Autonomous Database (MV2ADB) is a tool developed by Oracle (thanks Ruggero Citton, great work!) to fully  automate the process of migrating data both from on-premise as well as OCI Classic Gen 1 to Autonomous Database Cloud on OCI.

Data migration and loading to an Autonomous Database can now be performed using a single mv2db command which internally performs an Oracle Data Pump Export, moves the dump file to Cloud Object Store and also performs an Oracle Data Pump Import followed by a recompilation of the schema as well which was migrated.

The mv2adb tool can be downloaded via the  MOS Note 2463574.1 MV2ADB : move data to Autonomous Database in “one click”  which has a lot of good information about the various modes in which the mv2adb tool can be used like auto, expdp, impdp, createbucket ,putdump etc as well as a complete listing of the parameters which can be used in each case.

When we run mv2db tool with the auto option, it internally will run the expdp, putdump and impdp operations automatically.

Let us have a look at some examples of using mv2adb tool to move data from an Oracle 12c database hosted on OCI Classic Gen 1 to an Oracle 19c Autonomous Transaction Processing (ATP) database.

Install mv2adb on the OCI Classic Compute Node

[root@SITOIC01db mv2adb-2.0.1.80]# cp /home/opc/mv2adb-2.0.1.80.tar.gz /opt

Create the mv2adb configuration file

We need to encrypt the source database SYSTEM password, the target ATP database ADMIN password and also the authentication token of the Cloud Tenant.

We use the mv2adb encpass command for the purpose (we run it each time for the particular user) and store the encrypted passwords in the mv2adb configuration file.

[root@SITOIC01db mv2adb-2.0.1.80]# export MV2ADB_HOME=/opt/mv2adb-2.0.1.80

[root@SITOIC01db mv2adb-2.0.1.80]# cd $MV2ADB_HOME

One thought on “Data migration to Autonomous Database using MV2ADB

  1. Dan

    Hi. Nice post, as usual. How feasible this method is when your source database has around 10 TB of data?
