I can't test the whole function since it seems to be available only to Gold users (and I'm not ready to become one because I'm not convinced MMV5 is even usable for me). I can't use the free Edit Dead Links function because my old and new paths would both be available.
I need this function as part of a cloning process - cloning a library and database from a local drive to a USB flash drive. I need to change the flash drive's database to point to the music library on the flash drive - different drive and different path. The only way the links in the cloned database would be broken would be if I moved to a different computer after cloning the database
Update:
It looks we would be unable to use a Gold license - even if it gives us the function we need - without radically changing our configuration. A Gold license allows for 3 PC implementations or 2 PCs and one USB copy. For MMV4 we have almost 12 portable implementations of MM ... even though only one is used at a time and 3 are for various aspects of maintenance. All use cloned copies of a single "master" database. We could probably reduce the configuration down to 4 copies - one on a PC and 3 on USB flash drives, but it sounds like that would still require at least 3 licenses (since each supports only one USB copy). And we would have problems cloning the database ... unless there is a way to copy between separately licensed Gold MMs.
I don't mind paying for multiple licenses - I should probably donate something even if we don't go Gold - but it looks like I'll be paying for less function in Gold MMW5 than we had in free MMW4. Yes, there are a number of features in Gold, but none (that I've seen) that we would ever use.
This is frustrating. It looks like we will definitely be hobbled by moving from MMW4 to MMW5.
