====== Upgrade From v8.0 or v8.1 ======
Upgrading from version 8.0 or 8.1 to version 8.2 is very simple. If MongoDB is version 8.2 or above the DV2000 8.2 install can be run directly.

Upgrading to 8.2 can take a good deal of time depending on the number of messages your system has. In version 8.2 we store all message information in the database which provides additional features as well as an increase in speed. Previously this information was stored multiple files located within a mailbox folder.

If your database is older than 8.2 or you wish to upgrade it prior to the installation of DV2000 8.2 follow these procedures.

===== Requirements =====
  * DV2000 running 8.0 or above.
  * DV2000 license updated to support Dialogic SU543 (for SIP only systems).
  * CPU supports AVX (Advanced Vector Extensions).

===== Pre-Upgrade =====
  - Download the latest 8.2 install from the downloads section located [[download:home|here]].
  - Download the latest version of MongoDB from the downloads database section located [[download:home|here]].

===== Procedure =====
==== Database ====
If the database is any version older than MongoDB version 8, follow these steps before installing DV2000 8.2. This procedure typically takes less than three minutes.

===== Finalize =====
  - Confirm configuration.
  - Verify telephony lines start.
  - Make a test call to the DV2000 to ensure integration is still working.
