Archived - Mac OS X v10.4: Issues migrating to Mac OS X v10.5 or later via network connection and Migration Assistant

This article has been archived and is no longer updated by Apple.

Symptoms

When using Migration Assistant or Setup Assistant to migrate files via a network (Ethernet or AirPort) from a Mac running Mac OS X v10.4.11 to a Mac running Mac OS X v10.5 or later, you may see the message "Network connection failed" and the migration may not work. This may happen after being prompted to enter a six digit passcode twice.

Resolution

First, complete the following steps.

  1. Set the firewall of the Mac running Mac OS X v10.5 or later to "Allow all incoming connections" (in Security preferences, in System Preferences).
  2. Turn off the firewall of the Mac running Mac OS X v10.4.
  3. Run Software Update on each Mac to ensure all software updates have been installed.
  4. Attempt to migrate again.

If the issue persists, try one of the workarounds below.
 

Use a FireWire cable

If the issue persists after you've completed the steps above and both Macs have a built-in FireWire port, use a FireWire cable to perform the migration.
 

Use an external USB drive

If you have an external USB hard drive or storage device available with sufficient free space, you can use it to hold a disk image of the original Mac in order to migrate its files:

  1. Attach an external USB hard drive or storage device that has enough space to hold the contents of your Mac OS X v10.4-based Mac's hard drive.
  2. Start the Mac OS X v10.4-based Mac from your Mac OS X v10.4 installation DVD.
  3. Select your language, then choose Utilities > Disk Utility.
  4. Select your startup volume in Disk Utility.  The default name is Macintosh HD.
  5. Click the "New Image" icon in the Disk Utility tool bar.
  6. Click Save, and designate the the disk image to save on the USB hard drive.  Enter the administrator password if prompted.
  7. Once the imaging process is completed (which may take an hour or more), shut down the Mac OS X v10.4-based Mac
  8. Connect the USB hard drive to the Mac OS X v10.5 or later-based Mac.
  9. Mount the disk image created in step 6.
  10. Open the Migration Assistant in the Utilities folder.
  11. Select "From Time Machine backup or other disk," then click Continue.
  12. Select the disk image on the external disk in the "Select the System to Transfer" list, then click Continue.
  13. Follow the instructions in Migration Assistant to select the items you want to migrate.
     

Try these Terminal commands on the Mac OS X v10.4.11 system while logged in as an administrator

  1. sudo -s (if prompted, enter admin password and press return)
  2. echo "limit maxfiles 100000" > /etc/launchd.conf
  3. Restart the Mac OS X v10.4.11 system.
  4. Attempt the migration again.
  5. After migration completes or fails, remove the changes made in step 1 by entering this command in Terminal on the Mac OS X 10.4.11 system:  sudo rm /etc/launchd.conf (if prompted, enter admin password and press return).
  6. Restart the Mac OS X v10.4.11 system.

Other methods

If one of the Macs does not have a FireWire port and no external USB hard drive or storage device is available, you can transfer files to and install applications on the Mac OS X v10.5 or later-based Mac with one any of these methods:

  • Use File Sharing to transfer files between the computers.
  • Burn one or more discs containing documents on the Mac OS X v10.4-based Mac, then insert the disc(s) into the Mac OS X v10.5 or later-based Mac to copy the files off of the disc(s).
  • Install applications on the Mac OS X v10.5 or later-based Mac using the discs you originally used to install the applications on the other Mac.
