The archive function of the TC is great, and fast, but I can't figure out a quick way to do the reverse.
There isn't one. 😟
Your best bet is simple: keep the "archive" disk "on the shelf" in case you need the backups, and let Time Machine start fresh on the new Time Capsule. You can always browse and restore from the old backups, by connecting the drive, double-clicking the sparse bundle to mount it, then use the +*Browse Other Time Machine Disks+* option (hold down the
Option key while selecting the TM icon in your menubar, or right-click the TM icon in your Dock).
But if you're really determined, you might be able to use the *Time Capsule and Mac OS X v10.6: How to transfer your back up from an existing Time Capsule to a new one* section towards the bottom of this Apple article:

Since you no longer have the old TC, connect the "archive" disk directly to your Mac, mount the sparse bundle, and use the rest of the steps listed.
Since you're on 10.6.3, you can skip steps 8-13; effective with 10.6.3, Time Machine automatically resizes the maximum size of sparse bundles to the size of the volume they're on.
