Renaming the Transaction Log after you Restore

When you rename or move all other files in the database, you should also do the same for the log file.

To move or rename the log file, use the Transaction Log utility (dblog). You should run this utility:
Note: The database server must not be running on that database when the transaction log file name is changed.

You can also use dblog to rename the transaction log, even if you have not restored the database, given certain restrictions. You can access the Transaction Log utility from the system command line, using the dblog command-line utility. See Utility Guide > dblog Database Administration Utility.
