About NetBackup Enterprise Vault migrator registration
The NetBackup Enterprise Vault migrator is a COM server that is shipped with the NetBackup 7.1 or later versions. In addition, the NetBackup Enterprise Vault migrator also ships with all Enterprise Vault releases before 7.1, including Enterprise Vault 8.0 SP2 or later. However, from the Enterprise Vault 8.0 SP3 release, the NetBackup Enterprise Vault migrator ships only with NetBackup.
When NetBackup 7.6 is installed, there is a possibility that the NetBackup Enterprise Vault Migrator gets installed twice in some customer's configuration. The migratory can get installed during NetBackup 7.6 installation and also during the Enterprise Vault installation (version EV 8 SP2 or an earlier version).
The following list describes the different scenarios that can arise depending on whether NetBackup is installed before Enterprise Vault or vice versa:
NetBackup 7.1 or later 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 7.1 or later version of the Enterprise Vault migrator is installed. When that happens Enterprise Vault uses the NetBackup Enterprise Vault migrator that is installed with NetBackup 7.1 or later. 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 7.1.
In this scenario, the NetBackup 7.1 or later version of the NetBackup Enterprise Vault migrator was installed when NetBackup 7.1 or later 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 7.1 and later. This version is also not the appropriate version for Enterprise Vault to use. Again, it is important that Enterprise Vault use the migrator that NetBackup 7.1 or later is registered with.
You should ensure that Enterprise Vault uses the Enterprise Vault migrator that was installed with NetBackup. To register the correct version, you must manually register the NetBackup Enterprise Vault migrator that is installed with NetBackup 7.1 or later. Register the migrator after the Enterprise Vault installation is complete.
