Eric, One way to migrate the clients from ADSM 3.1 to TSM 4.2 . On the client, in the dsm.sys file, change the serveraddress that is pointing to the ADSM 3.1 to TSM 4.2 .
Since the system with TSM 4.2 is not aware of the client, when the client does its first backup to the TSM 4.2 it will be a full backup. Then the next backup will be incremental. If you have a lot of clients, I would only have about 10-20 clients pointing to the TSM 4.2, becuase if you point all the clients to the TSM 4.2 there is going to be a lot of network traffic. If you want a file that is on the ADSM 3.1, just change the serveraddress back to the original ip address. Over time the data on ADSM 3.1 will expire. Also in the dsm.sys file I would make a note, something like this: ****************************** * If file can not be found * change serveraddress to * xxx.xxx.xxx.xxx * ADSM 3.1 * Once restore is complete change * serveraddress back to * xxx.xxx.xxx.xxx ****************************** Its just a note to remind you that if you can't find the file, the file could still be on the ADSM 3.1 .
