I generally clone to unallocated drives. First clone the SRP, then the OS partition.
It is simple to change from IDE to AHCI in Windows 7, it only takes a change of one registry key: HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\Msahci Click once on the msahci registry folder and double click the start key and change its value to 0, save it with an OK, and then reboot and during the reboot change the bios to AHCI. http://support.microsoft.com/kb/922976
Also after the clone, check your drive alignment, as going HDD to SSD may result in it being off: http://www.sevenforums.com/tutorials/113967-ssd-alignment.html
A clean install the first time to the SSD would be best despite all of the above info.
