When you have finished configuring your agents and domains, you should export an agent list to a secure location. An exported agent list serves as a backup against manager hardware failures or other problems that may require you to reconstruct your manager. You also need to export the agent list if you intend to move, upgrade, or rename a manager. Symantec ESM lets you export the agents list to a location that you select. You need this list to use the Symantec ESM re-register feature, which can automate the reregistration process.
To export an agent list
On the enterprise tree, right-click a manager and then click Export Agent List.
In the Select Format dialog box, select the format of the file.
Navigate to the location where you want to save the agent list and click Save.
Click OK on the message prompt that recommends that you take a backup of the agent list.
