Supported versions of Enterprise Vault in Compliance Accelerator and Discovery Accelerator environments

All Enterprise Vault servers in all Enterprise Vault sites in an Accelerators environment must run the same version of Enterprise Vault. For example, when using Discovery Accelerator with two Enterprise Vault installations, you cannot have one site that runs Enterprise Vault 9.0 and another that runs Enterprise Vault 8.0 SP4.

If the major version of Compliance Accelerator or Discovery Accelerator is the same as the version of Enterprise Vault, the minor version (Service Pack) of Compliance Accelerator or Discovery Accelerator must be the same as, or later than, the minor version of Enterprise Vault.

For example:

You can run Discovery Accelerator 9.0 with Enterprise Vault 8.0 SP4 servers, but not Discovery Accelerator 8.0 SP4 with Enterprise Vault 9.0.
You can run Discovery Accelerator 8.0 SP4 with Enterprise Vault 8.0 SP2 servers, but not Discovery Accelerator 8.0 SP2 with Enterprise Vault 8.0 SP4.
