Unlink it first; then re-link it to the new version.
But; running your media on external drives; be careful. That can be abottle neck if not connected at high speed. (usb for example would be bad)
My external drive are connected by USB.
What do you mean by bottleneck, that the transfer of info could be greatly slowed, leading to a crash for example?
How is it bad other than slowness, can data be damaged?
I'm planning on buying a workstation with a massive internal drive soon and running the projects from the C drive.
As far as external drives though, what connection other than USB do you recommend, firewire or something else?

Externals should only be eSATA, and internally you should have at least three physical SATA drives for comfortable editing. Running projects off the C drive can almost be considered a capital crime.
Harm, so when I get the workstation there should be at least three internal SATA drives(in addition to the C drive) named F, G. H or whatever?
Isn't it better to have Premiere access everything from one drive?
Why is running projects off of C: bad as long as everything is backed up and the HD has enough space to hold all the files associated with the project?

Have you ever tried smoking a cigar and having a glass of port at the same time? Your cigar will get all wet and extinguish. You can't do those two thing at the same time. You have to do it consecutively. The same applies to disks. You can't access two files at the same time, let alone multiple files. Your C drive needs to be accessed by the OS and programs, for loading a program, for housekeeping tasks of the OS, for services running, for other processes, possibly for pagefile access, for temp files, etcetera. Ideally you would have different disks for all of these file accesses so they can all be accessed at the same time instead of in sequence, but that is not practical. Your C drive will be busy a lot of the time, because of all the services and processes running. Access to the project file, to preview files, to media files, to conformed audio files, to peak files, to effects and transitions or plug-ins will introduce a lot of waiting for one action to finish, before the next action can be started if this all occurs on one drive. Of course, the faster the drive the less the impact of waiting.
As a rough rule of thumb, one sees average transfer rates with modern disks:
USB2: 20-25 MB/s
FW400: 30-35 MB/s
FW800: 50-60 MB/s
SATA: 80-100 MB/s (and eSATA)
Hence the suggestion to use SATA or eSATA disks only and as many of them as is feasible.
Thanks, Harm. My laptop won't accept Sata external drives which is another reason a workstation is becoming a necessity.
I'll get SATA drives on my new computer but will probably post in the hardware section in the near future to fine tune
what exactly I'll purchase.
It is advisable to install the Premiere on C: though, just keep the the projects on other drives?
Yes, it is.
