This topic describes how to migrate an EBS Virtual Database (VDB) from one target environment to another.
There may be situations in which you want to migrate a virtual database to a new target environment, for example when upgrading the host on which the VDB resides, or as part of a general data center migration. This is easily accomplished by first disabling the database, then using the Migrate VDB feature to select a new target environment.
There are three components for any EBS environment - dbTechStack, Database, and appsTier. Whenever we create virtual copies for any EBS environment, we provision these components in the following sequence: (1) dbTechStack (2) Database (3) appsTier.
We can only migrate the EBS database (VDB) with the following prerequisite.
Prerequisite
You should have already set up a new target environment that is compatible with the VDB that you want to migrate.
Procedure
-
Login to your Delphix Management application.
-
Click Manage.
-
Select Datasets.
-
Select the VDB you want to migrate.
-
From the Actions menu (...) select Disable.
-
Click Disable to confirm. When the VDB is disabled, its icon will turn grey.
-
From the Actions menu (...) select Migrate.
-
Select the new target environment for the VDB, the user for that environment, and the database installation where the VDB will reside.
-
Select Migrate to confirm your selections.
-
From the Actions menu (...) select the Enable
-
Click Enableto confirm.
Within a few minutes, your VDB will restart in the new environment, and you can continue using it.
-
You need to provision the EBS dbTechStack on the new target environment with a similar DB name VDB that you want to migrate.
-
EBS appsTier vFile cannot be migrated, you need to re-configure the EBS appsTier by modifying the custom configuration for Target DB server node information to the target environment where VDB is migrated.
