How can I move my OSX Lion installation from my 500GB HDD, to my new 250GB Solid State HDD?
Re-installing OSX Lion is not an option.
there are a few solutions but the 2 most usefull to me are these :
for both solutions you'll need an SATA 2 usb enclosure or something like that
you can use an app like carbon copy cloner to make a copy on the new ssd and then just replace it.
or you can boot from a OS X dvd and use disk utility to clone the drive
select your language. Don’t worry: You're not installing Mac OS X again - this is just what you have to do to get to Disk Utility. When the menu bar appears, select Disk Utility from the Utilities menu.
When Disk Utility opens, you'll want to select your source. This is the hard drive you want to clone . After you have a source, select the Destination. This is the ssd you want to save the backup image to.
Click Restore and you'll end up with a perfect copy of your hard drive.
Replace the drive with the SSD and your good to go

You can create a Time Maschine Backup on an external drive, plug the new HDD in and boot from the install DVD while the Time Maschine HDD is connected to the system. The installer will ask you if it should use the data from the Time Maschine HDD. After you did this, everything will be exactly like on the old HDD and no more configuration has to be done.
OK, this comes close to a new installation, but at least it should be bullet proof and you will have everything like before.
You should be able to just copy over the files from one disk to another, as the Apple boot loader looks for a file named
So, you just should format your new SSD using Disk Utility, making sure it has the GUID Partition Table scheme (under options in the Partition tab of Disk Utility), then copy over the files from one volume to the other using
You can do the copy from a current OS X install, but not the one you're copying from (since a running OS constantly modifies files, therefore risking corrupting the copy) or using
Note: I didn't test this myself. But you could definitely try: since it's a copy, you don't risk anything. As always, a proper backup would prevent you from mistakes.

Edit: After Manuel's response, and checking with small disk images on a backup drive, it seems that Disk Utility is filesystem-aware, which allows it to copy files from larger volumes to smaller ones, provided that the contents fit the smaller drive.
For me, OSX Lion, trying to clone my 750 Gb HD to an external 500 Gb using Disk Utility, didn't work although only some 250 Gb were actually in use. While the cause to this may be an error on my side, some people might have the same problem..
The solution was to shrink the Macintosh HD partition on the local disk to a size smaller than 500 Gb using Disk Utility which is quite a fast process. After doing this cloning to the 500 Gb external disk went without problems.
Hope this is helpful.
I just did this. I got a 256GB SSD for $175 and installed it in my late model 17" Macbook Pro. I then took the 750GB 7200RPM hard drive and installed it in the optical drive bay using this tray / adapter...
I had already formatted the new SSD in a USB enclosure.
When I rebooted, the machine found the regular hard drive now in the optical bay, and booted Mac OSX from it like normal. Both drives are available in Finder. Write tests, read tests and running a VM from the SSD worked fine.
I rebooted the machine, and held down [Command] + [R] to boot into the Restore utilities. Ran the Disk utility and used Restore to copy the contents of the hard drive to the SSD. I had removed all of my virtual machines from the hard drive first, so there was only 136GB of files on the hard drive. Transferring that to the SSD took about 30 minutes.
After the copy to the SSD completed, I ran the Startup Disk utility, set the machine to boot from the SSD and rebooted.
Once the machine was up and running on the SSD satisfactorily, I copied all of the virtual machines except one back to the old 750GB hard drive. The VM that I use most, I copied to the SSD.
Then I installed this script onto my machine...
and now I can dismount, and spin down the old hard drive when I am not using it. Here's the new configuration...
17" Macbook Pro Late 2011 (MacBookPro8,3 (17")) 256GB San Disk Ultra Plus Sata 6 SSD mounted in hard drive slot Existing 750GB 7200 RPM hard drive moved to optical bay
OS, software and main VM is on SSD. 750GB hard drive is used for VM storage utilization. Spinning disk can be dismounted and spun down on demand, saving battery.
damned cool machine!
