</WRAP>

===== Requirements =====
  * Existing DV2000 running any version 6.3
  * License for DV2000 8.
  * MongoDB36.exe which is available [[https://downloads.duvoice.com/tools/mongodb36.exe|here]].
  * DV2000 [[download:home|8.2]] install.
  * Knowledge of the DV2000.

===== Instructions =====

==== Preparation ====
  * Ensure there is enough disk space. We cannot predict how much space will be required, however a good rule of thumb would be to have triple the space used of an existing backup file located in C:\VMBACKUP. These files have the extension .vmb.
  * DV2000 service must be stopped. This can be performed either via Activity Monitor or Windows Services.

==== Backup ====
Backup the existing database. This will ensure if the process fails a full copy of the database has been saved.

  - Run Backup from the Windows start menu DV2000 Utilities | Backup, or from the command line via dvbackup.exe. \\ {{:images:vs8:upgrades:v6backup.png?direct|}}
  - Do not check **Include Messages**. Messages are not stored in the database and therefore do not need to be backed up.
  - Choose **Manual Backup** and select a file name and location you can remember. We suggest C:\VMBACKUP\predbupgrade.vmb.

==== Data Export ====
Using the following method will export the existing database so that we can be restored later. No data will be deleted during this step.

  - Open a CMD or Windows Powershell process window.
  - Run the following command. \\ //**mongodump -d bandon -o c:\oem\dbv2**//
  - Verify the folder //c:\oem\dbv2// contains a folder called //bandon// and it contains multiple .json and .bson files of various sizes.
  - If the folder is blank or contains no files, check for any errors while running //mongodump//.
  - Leave this window open for performing the restore later.

==== Database Uninstall ====
We must first uninstall the existing database server from Windows Settings | Apps & features. This can also be performed using the control panel via //Programs and Features//.

  - Choose MongoDB. \\ {{:images:vs8:upgrades:winapps-mongo-uninstall.png?direct|}}
  - Click Uninstall.
  - Ensure the removal of existing databases is checked or the new install will fail. \\ {{:images:vs8:upgrades:mongodb-uninstall.png?direct|}}

==== Database Upgrade ====
Run the new database upgrade. It can be downloaded [[https://downloads.duvoice.com/tools/mongodb36.exe|here]].

==== Data Restore ====
This will restore the database content into the new database using the new server.

  - Using the same process window before or from a new CMD or Windows Powershell process window.
  - Run the following command. \\ //**mongorestore c:\oem\dbv2**//

==== Verification ====
  - Open Mailbox Administration.
  - Verify it shows your existing mailboxes.
  - Verify a few mailboxes show information by double-clicking on one or more.
  - If you are certain the restore was successful you may delete //c:\oem\dbv2// to save space.

==== Upgrade ====
  - For SIP enabled systems:
    - Uninstall Dialogic HMP and reboot system when requested to do so.
    - Install latest Dialogic HMP and follow the steps in this [[https://support.duvoice.com/vs8/install/dialogic|guide]].
