Important notes before you start...


1. Hyper-V Cluster Support: The configuration migration tool cannot be used to move the Altaro VM Backup configuration between nodes in the same cluster. It is suggested that in this case a dedicated machine is used for Altaro VM Backup.


2. VMware vCenter: If you have a vCenter server added to your Altaro VM Backup console, kindly contact support@altaro.com before proceeding.


3. If you are migrating to a Hyper-V Host that was already managed by the previous installation, please note that this is not currently supported and it is suggested to use a dedicated machine for Altaro VM Backup.


4. If you previously had a mixed infrastructure (Hyper-V and VMware), please note that this is not currently supported and it is suggested to use a dedicated machine for Altaro VM Backup.


5. You must be running at least 8.5.20 in order make use of the migration tool.



Section A - Migrating to a new machine


Altaro VM Backup automatically backs up its configuration to your configured primary locations. This allows you to restore the configuration to another machine in case of a disaster or if you need to migrate it to another machine. The configuration is saved in the 'ConfigBackup' folder in the configured backup location.


It is important to note that:

  • The Altaro VM Backup Console must be closed
  • The target machine being used to restore the configuration must have a clean Altaro VM Backup installation


To start the migration, proceed as follows:

  1. Install the latest version of Altaro VM Backup on the new machine

  2. Uninstall Altaro VM Backup from the old machine. This is a really important step; failure to do so could result in data corruption from having both consoles running at the same time.

  3. Browse to C:\Program Files\Altaro\Altaro Backup and right-click on "AttachConfig.exe" and [Run as Administrator]

  4. The AttachConfig tool will pop up:



  5. Click [Next] to proceed and leave [Altaro VM Backup] selected in this case. Then select the Backup Location by browsing to it or enter the network path as well as the network credentials for the backup location. This needs to be supplied as previously configured in Altaro Backup Locations screen.

    The [Master Encryption Key] needs to be the same that was configured in the previous installation. Make sure it is entered correctly and identical as otherwise encrypted backups will start fresh.

    Once you provide all information, click [Next] and then if you are sure that the encryption key was entered correctly click [OK] to proceed.



  6. If the tool finds multiple configuration backups within the entered backup location, you will get a choice via a drop-down menu:


    You will see the machine name of the previous installation listed, once you pick the desired one. Click [Next]



  7. After it goes through a couple of steps to map previous hosts etc...you will be prompted to enter credentials for any network locations you had added to the previous installation. Once all data has been entered, click [Next] or if you would like to enter them afterwards, you can skip it.



  8. You should finally get this screen that configuration has been successfully imported. You can proceed to Section B in order to complete your migration.




Section B - Completing your Migration


Next, make sure to follow the steps below in order to complete the migration:

  1. Go to [Hosts] and click the Install button next to each host in order to re-authenticate to your host

  2. If your installation was connected to CMC, click on the [CMC] option and add the installation. This will be added as a new installation, then it's important to delete the old disconnected installation.

  3. Go to [Backup Locations] and re-enter the credentials for Network Paths, Altaro Offsite Servers or the Connection String for Azure/Amazon S3/Wasabi accounts. Simply click on the pencil icon to edit the current location.

  4. If you didn't have an Altaro Offsite Server (Managed by CMC) Backup Location added to your Altaro VM Backup, you can skip this step. Go to Step 5.

    If you did. your location will now be marked as disconnected. You will need to go to your CMC, open your Altaro Offsite Server and click on [Choose VMs to Back Up]

    Select the Altaro VM Backup Installation, as you can see we are picking the new one here, old one is marked as disconnected. Then, select the Unmanaged location and match it with the AOS account.


    Pick the VMs you'd like to backup to the Altaro Offsite Server, click [Next] and [Save]

  5. Go to [Notifications] and re-enter the credentials if you were using authentication with the SMTP server. If you didn't have this set up, you can skip this step.

  6. If your installation has a Proxy configured, click on the [Settings] icon > [Proxy Settings]. If you didn't have this set up, you can skip this step.

  7. You're all good to go! All backups will now keep backing up to any existing backup data from the previous configuration.
