If your RAID partition isn't aligned right for SSD, you'll need partition management/backup software that can realign.
First clean up the disk, temp files, Windows Update caches, service pack uninstall backups, restore points, blah blah blah, make sure chkdsk /f is clean, and begin setting the current environment as if you had an SSD already. Finally do a defrag to speed up the next step that you may have to do more than once. Install any vendor software for the SSD and run the Windows tweaks to prepare the environment, eg disable defrag, prefetch, auto boot optimize, hibernate, etc. Most important, if you are changing your controller config (disabling RAID, going from IDE to AHCI, etc) make sure you install the drivers for it now or you will get unmountable boot volume.
When it's all set and ready to go just like you want it on your SSD, run something like Paragon to align the partition on your disks. Start partition at align=1024 (K) is great as it's divisible by any possible conceivable power of 2 block and page size of any SSD out there. You can skip this step if the imaging software is able to realign on the fly. Just use diskpart to verify that it did what it was supposed to and it's aligned.
And finally make a image with a Ghost/Acronis tool. While you wait for your SSD to arrive, you can image a spare single HDD with your partition backup for final testing, and boot from it via BIOS boot device hotkey to make sure you can boot in AHCI mode with proper drivers, etc if your non RAID ports require a non RAID driver. You should be able to boot to Windows, log in, with the test drive being C: and your RAID being D. Boot back to your RAID, make changes if needed, redo the partition backup, etc. until all you need is your SSD.
Doing this before hand gives you some final quality time with your loyal RAID and saves your SSD from 100s of GB of pointless wasteful rewrites on the first night. Not really a wear and tear concern so much as writing over the capacity right away and putting the garbage collection into overtime (even with Win7, doubtful that the partition copying over and over is sending TRIM for the 100s of GB etc).
Then when your SSD arrives, you're up in mere minutes with a SATA to SATA image restore from your RAID to SSD and reboot with the new boot device.
Then put the image you used when it's all done on an external as backup in case you experience failures with the SSD in the first couple weeks/months of use and update it periodically. And be sure to supplement it with regular daily/weekly incremental/differential backups.
Finally, break the RAID and wipe the drives or whatever you plan to do with them.
The transfer kits will be terrible if they are USB 2.0 cables.
