The second technote listed covers that. If you look at the properties of you Archive in the Vault Admin Console on the Index tab you will see the option to change the location for your index. You could start at Step 2 if you are going through the VAC.
Change the index location for one archive
1. Right-click the list of index volumes and, on the shortcut menu, click Select All. Alternatively, multiple index volumes can be selected as follows:
- To select single index volumes, hold down Ctrl and then click the index volumes.
- To select a group of index volumes, click the first index volume then hold down Shift while clicking the index volume in the group.
2. Right-click the selected index volumes and, on the shortcut menu, click Set Index Volume Offline. There is a warning that index volumes cannot be searched when they are offline. Click Yes. There is a confirmation that the operation has been queued. Click OK. The status of the index volume changes to Offline.
3. Click the Advanced tab of the archive's properties and make a note of the Archive ID. To copy the Archive ID to the Windows clipboard, double-click the ID to select it, then right-click it and, on the shortcut menu, click Copy.
4. Copy the existing index folder to the new location. Copy the whole folder, without changing the name.
5. When the copy is complete, click Change Location.
6. On the Index Volume Location dialog, select the index server that manages the new location and then select the location where the index folder was copied. Click OK. The index location is changed and all the index volumes are automatically set online.
7. Delete the original index folder.
