Moving MM to a new computer
Introduction
If you want to move MM to a new computer (or hard drive) but retain your database, follow these steps. If these steps are followed correctly, all information that is maintained by your database will be retained, including PlayHistory, PlayCounts, Dates Added, PlayLists and all other fields within MM.
Copying your database
Your database is located at:
Windows XP: C:\Documents and Settings\<USERNAME>\Local Settings\Application Data\MediaMonkey
or
Windows Vista / Windows 7: C:\Users\<USERNAME>\AppData\Local\Mediamonkey
and is called MM.DB (note that you will have to enable viewing of hidden Files and Folders to find this file).
After installing MM on the new computer, put your database in the correct location (as noted above) on the new computer.
Optionally, you may also want to save your registry info as well, @ HKey_Current_ User\Software\Mediamonkey
Moving your music to the new PC
Next, you'll have to move all the music from the old PC onto the new one, making sure that the file directory for each track stays the same as on the old PC (with the exception of drive letter, though that can remain the same.)
Installing the update drive-ID script
After you do all of that, install this script to your new PC. To install this script, first shut down MM. Next, copy the contents in the 'Code:' box at the link provided into notepad. Save the file as 'MM_HDDSerial.vbs' (without the quotes) in your C:\Program Files\MediaMonkey\Scripts folder. Next, within that same folder, find 'Scripts.ini'. Open this file with notepad and copy the following lines and paste them onto the end of the file, then save.
Copy these lines into Scripts.ini:
[HDDSerial]
FileName=MM_HDDSerial.vbs
ProcName=Change_HDD_Serial
Order=99
DisplayName=Move Device Content
Description=Corrects broken links after exchanged harddrive
Language=VBScript
ScriptType=0
Running the script
Now you're ready to run the script. Open MM (if you are using Windows Vista or Windows 7, right click on the MM icon and choose "Run as administrator" even if your Windows user account has administrative rights) and run the script at Tools -> Scripts -> Move Device Content. If you receive any errors or the script doesn't appear under Tools -> Scripts, check that you have installed the script correctly, and/or try restarting MM.
Running the script will change the drive-ID within the MediaMonkey database to recognize your new drive, and all your database information will be retained. If you can play your music from MM, and tracks do not 'grey out', then you have successfully moved your MM installation to a new computer.
Alternative
The Update Location of Files in Database addon is an alternative to the script and can also handle changed paths on the new drive: http://www.mediamonkey.com/forum/viewtopic.php?f=2&t=63823&hilit=Update+Location+of+Files+in+Database
