To provision a virtual database (VDB), you can either use an existing dSource snapshot or use another VDB snapshot for VDB to VDB provisioning. A snapshot is a timeflow created in a dSource or VDB.
An environment can be associated with only one dSource/VDB at a time.
Prerequisites
-
You should either have linked a dSource from a staging instance following the instructions in "Linking a Yugabyte dSource," or you should have already created a VDB from which you intend to provision another VDB.
-
A Yugabyte target environment must be set up with the requirements as described in Yugabyte support and requirements.
-
A Yugabyte binary with the same version as the source database must be installed on the target host.
