Hello Hesam, 

if your host /opt/ partition has reached to 12T limitation then you cannot make the archive searchable. 

This is explained in the official documentation like this :

Note: Any events that are brought from an offline archive into the online archive count as part of the total 12 TB (or license determined) storage limit. You do not want the offline archives that you bring back online to encompass the entire storage limit. Use discretion when bringing offline archives online, and be sure to make them offline again when you are done working with them.

How can I solve my problem - that depends on your storge definition.

Best Regards, 

Daniel

Sorry mate, 

what is the connection between you cannot restore the archive because your system reached the max limit of 12 TB and the new server ?
