Migration from G4 Powerbook(partitioned) to new IMAC

Question

I am tried to use Migration today, from G4 Titanium DVI Powerbook(partitioned) #1 MacTiger 10.4.11- 14GB, #2 OSX 9.9GB, #3 OS9 4GB to my new IMAC that I have had for a couple of weeks. When I had to enter the name info, it kept on telling me that I had to change the names as they were already existing. Began migration and it ran for 3 hours or more then stopped with 2 hours 58 minutes remaining on the clock. I let it go for over another hour. Nothing happening. Tried to cancel but 3 new icons were on my IMAC desktop. Rainbow wheel goes round and round etc. on IMAC. I then held down the power button on the G4 to power off. The 3 new icons on my IMAC desktop, I dragged them to the trash. I'm all in a sweat just writing this down. Who would like to hold my hand as I walk through the valley of the shadow........
Thanks for your reading, responding, succeeding. You guys always come through. Are PC people this fortunate?

I'm not sure what you are asking. Yes you can change the name of a user account, but it's a bit complicated. It would be easier to simply transfer the files as I've outlined rather than trying to use Migration Assistant which will attempt to transfer everything in the user account, which is ill-advised. There are PPC components in your old system that you do not want moved to the new computer. PPC components can gum up the works on an Intel system.
Migration Assistant is an excellent tool but it's not the right tool when you are migrating from a PPC Mac to an Intel one. See the following:
A Basic Guide for Migrating to Intel-Macs
If you are migrating a PowerPC system (G3, G4, or G5) to an Intel-Mac be careful what you migrate. Keep in mind that some items that may get transferred will not work on Intel machines and may end up causing your computer's operating system to malfunction.
Rosetta supports "software that runs on the PowerPC G3, G4, or G5 processor that are built for Mac OS X". This excludes the items that are not universal binaries or simply will not work in Rosetta:
Classic Environment, and subsequently any Mac OS 9 or earlier applications
Screensavers written for the PowerPC
System Preference add-ons
All Unsanity Haxies
Browser and other plug-ins
Contextual Menu Items
Applications which specifically require the PowerPC G5
Kernel extensions
Java applications with JNI (PowerPC) libraries
See also What Can Be Translated by Rosetta.
In addition to the above you could also have problems with migrated cache files and/or cache files containing code that is incompatible.
If you migrate a user folder that contains any of these items, you may find that your Intel-Mac is malfunctioning. It would be wise to take care when migrating your systems from a PowerPC platform to an Intel-Mac platform to assure that you do not migrate these incompatible items.
If you have problems with applications not working, then completely uninstall said application and reinstall it from scratch. Take great care with Java applications and Java-based Peer-to-Peer applications. Many Java apps will not work on Intel-Macs as they are currently compiled. As of this time Limewire, Cabos, and Acquisition are available as universal binaries. Do not install browser plug-ins such as Flash or Shockwave from downloaded installers unless they are universal binaries. The version of OS X installed on your Intel-Mac comes with special compatible versions of Flash and Shockwave plug-ins for use with your browser.
The same problem will exist for any hardware drivers such as mouse software unless the drivers have been compiled as universal binaries. For third-party mice the current choices are USB Overdrive or SteerMouse. Contact the developer or manufacturer of your third-party mouse software to find out when a universal binary version will be available.
Also be careful with some backup utilities and third-party disk repair utilities. Disk Warrior 4.1, TechTool Pro 4.6.1, SuperDuper 2.5, and Drive Genius 2.0.2 work properly on Intel-Macs with Leopard. The same caution may apply to the many "maintenance" utilities that have not yet been converted to universal binaries. Leopard Cache Cleaner, Onyx, TinkerTool System, and Cocktail are now compatible with Leopard.
Before migrating or installing software on your Intel-Mac check MacFixit's Rosetta Compatibility Index.

Transferring data with Setup Assistant - Migration Assistant FAQ
Because Migration Assistant isn't the ideal way to migrate from PowerPC to Intel Macs, using Target Disk Mode or copying the critical contents to CD and DVD or an external hard drive will work better when moving from PowerPC to Intel Macs.
Basically the instructions you should follow are:
1. Backup your data first. This is vitally important in case you make a mistake or there's some other problem.
2. Connect a Firewire cable between your old Mac and your new Intel Mac.
3. Startup your old Mac in Target Disk Mode.
4. Startup your new Mac for the first time, go through the setup and registration screens, but do NOT migrate data over. Get to your desktop on the new Mac without migrating any new data over.
4. Copy the following items from your old Mac to the new Mac:
In your /Home/ folder: Documents, Movies, Music, Pictures, and Sites folders.
In your /Home/Library/ folder:
/Home/Library/Application Support/AddressBook (copy the whole folder)
/Home/Library/Application Support/iCal (copy the whole folder)
Also in /Home/Library/Application Support (copy whatever else you need including folders for any third-party applications)
/Home/Library/Keychains (copy the whole folder)
/Home/Library/Mail (copy the whole folder)
/Home/Library/Preferences/ (copy the whole folder)
/Home /Library/Calendars (copy the whole folder)
/Home /Library/iTunes (copy the whole folder)
/Home /Library/Safari (copy the whole folder)
If you want cookies:
/Home/Library/Cookies/Cookies.plist
/Home/Library/Application Support/WebFoundation/HTTPCookies.plist
For Entourage users:
Entourage is in /Home/Documents/Microsoft User Data
Also in /Home/Library/Preferences/Microsoft

If you need to transfer data for other applications please ask the vendor or ask in the Discussions where specific applications store their data.
5. Once you have transferred what you need restart the new Mac and test to make sure the contents are there for each of the applications.
