After Migration to new Mac Pro, intermittent slow downs, SROD's

Question

I started with a my intel mac mini, Leopard OS was installed on an external Firewire drive, most applications were installed on another partition of that same drive. I bought a new mac pro 8 core, and an additional firewire external drive that I set up as my Time Machine drive on my old mac mini. I did a full backup of my old mac mini system and then attached the time machine drive and the other external hard drive to my new mac pro. I used the migration assistant to transfer files to my new mac pro. However, now there appears to be something occuring between my internal mac pro hard drive and the old external hard drive from my mac mini. When using some applications, Itunes, Logic Pro, Firefox, the ap will hang and appears to be trying to access files from the old external drive. I hope I'm being clear with what the issue is. I'm thinking duplicate files on this external drive and my internal drive are causing some problems? I need to know how to repair the issue, and preserve my data files?

Thanks for your quick response. I know I've been somewhat confusing here. I'm running the latest Snow Leopard update on my mac pro now.
Then please update your profile, as it still shows the mini and Leopard.
And I'll ask a Host to move this to the Snow Leopard > Time Machine forum.
All the aps and data were migrated onto the internal HD in the mac pro, and the aps and files and directory structures, etc. are still also on the external drive that used to comprise the OS of my mac mini. I'm thinking that may be part of the issue, but I'm new to Mac and not certain of that or how to fix the issues.
Depending on how you did that, I'm not sure everything on those partitions got on to the new Mac's HD. Check that first, via the Finder.
Let's start with iTunes and/or iPhoto.
First see if you have the same stuff in both places. Use the Finder to see how large each is on the external HD, and compare that to the iTunes and iPhoto folders on your internal HD.
If they're not on your internal HD at all, use these instructions to move them:
Moving your iTunes Music folder
Moving your iPhoto library
If the versions on the external are newer than the ones on your internal, delete the ones on the internal and use those instructions to move from the external to the internal.
But don't delete the versions on the external just yet. Eject and disconnect it, and make sure everything's fine. It won't hurt to leave the data there for a while, especially as long as it's disconnected.
If the music or photos on your HD are the same, or newer, hold down the Option key while starting iTunes or iPhoto. That will give you a prompt where you can select which one you want to use.
Once you've selected the ones you want, eject and disconnect the external. Then use as many apps as you can, to see if everything works properly and all your data is found.
Without knowing what other apps you have, and how they work, I can't tell in advance whether any others will be looking for the external drive. If you get error messages, you'll have to deal with each app that seems lost.
I'd be inclined to keep the old external "on the shelf" for quite a while, just to be sure nothing got missed.
Have you started doing Time Machine backups of the new Mac yet? When you do, you'll get a prompt about whether to "re-use" the Mini's backups. See #B5 in the Time Machine - Troubleshooting *User Tip,* also at the top of this forum. You probably want to select "Re-use," especially if there's a considerable amount of space on your TM drive.
