The NetBackup Enterprise Vault migrator is a COM server that is shipped with NetBackup 7.0. In addition, the NetBackup Enterprise Vault migrator also ships with all Enterprise Vault releases before and including Enterprise Vault 8.0 SP2. Starting with Enterprise Vault 8.0 SP3, the NetBackup Enterprise Vault migrator ships only with NetBackup.
When NetBackup 7.0 is released, it is possible that the NetBackup Enterprise Vault Migrator gets installed twice in some customer's configuration. It is installed once when NetBackup 7.0 is installed (version NetBackup 7.0+) and a second time when Enterprise Vault is installed (version EV 8 SP2 or an earlier version).
You should ensure that Enterprise Vault uses the Enterprise Vault migrator that was installed with NetBackup. The following list describes the different scenarios that can arise depending on whether NetBackup is installed before Enterprise Vault or vice versa:
NetBackup 7.0 is installed after Enterprise Vault (8.0 SP2 or an earlier version).
In this scenario Enterprise Vault is already installed and a version of the NetBackup Enterprise Vault migrator was installed with it. When the NetBackup installation starts, the NetBackup 7.0 version of the Enterprise Vault migrator is installed. When that happens Enterprise Vault uses the NetBackup Enterprise Vault migrator that is installed with NetBackup 7.0. You do not need to do anything to register the migrator; it is done automatically.
Enterprise Vault (8.0 SP2 or earlier releases) is installed after NetBackup 7.0.
In this scenario, the NetBackup 7.0 version of the NetBackup Enterprise Vault migrator was installed when NetBackup 7.0 was installed. When Enterprise Vault is installed, an earlier version of the Enterprise Vault migrator is installed and registered. This version of the migrator is not as new as the version that is installed with NetBackup 7.0 and it is not the appropriate version for Enterprise Vault to use. Again, it is important that Enterprise Vault use the migrator that NetBackup 7.0 registered.
To register the correct version, you must manually register the NetBackup Enterprise Vault migrator that is installed with NetBackup 7.0 after the Enterprise Vault installation completes.
