You can centrally manage your Double-Take licenses through the license inventory feature in the Double-Take Console. Ideally, you should select one machine in your organization where you want to maintain the license inventory because the license inventory does not communicate between machines.
By default, the license inventory feature is enabled. You can, and should, disable it on machines that are not maintaining your license inventory. To disable the license inventory, select Options from the console toolbar, deselect Enable license inventory, and click Save.
To manage your license inventory, select Manage Licenses in the toolbar.
The license inventory feature may not appear in your console if your service provider has restricted access to it.
You will see the following fields on the Manage License Inventory page.
Warning or error icon
Warnings indicate the license has not been activated, or it is temporary and will expire. Errors indicate the license has expired.
Serial Number
The serial number associated with the license
Product
The Double-Take product associated with the license
License Type
A short description of the type of license, including any expiration date or quantity information
Version
The product version number associated with the license
Server
The name of the server the license has been applied to, if any. If the same license key is used on multiple servers, for example with evaluation licenses, you will see multiple entries in the license inventory for each server that is using that license key.
Use the following toolbar controls to manage your licenses.
Import Licenses
Imports all of the license keys from a license inventory file into the license inventory. This is a file you may have received from Double-Take Software, or it may be from another Double-Take Console. Depending on the information contained in the file, you may be prompted to activate some of the servers in your license inventory.
Export Licenses 
Exports all of the license keys in the license inventory to a license inventory file. This is a file that you may want to send to Double-Take Software when upgrading keys for a newer release or when activating licenses. You may also want this file so you can store and back up your license keys.
Add Licenses 
Adds license keys into your license inventory. Enter the license keys in the Add Licenses dialog box in the space provided, separating multiple keys by a comma or by putting each key on a separate line.
Remove License 
Removes the selected license key from the license inventory. You can only remove license keys that are not being used by any server in the console.
Reclaim License 
Returns a license key that was no longer in use on a server back into the console's license inventory. This process should not be used for transferring an activated license to a new or rebuilt server, which is considered deactivation.
Activate 
Activates the license keys in the license inventory.
The activation process will automatically deactivate any licenses that have been uninstalled using the Double-Take Console.
The activation process will automatically upgrade any Double-Take Move version 6.0 or 7.0 license keys in your license inventory.
