I've just bought an SSD. I want to move my current arch install (ext4) there, but I'm not sure if I'll then be able to apply all the necessary SSD tweaks (partition alignment, basically).
If anyone's done this, what steps did you take to make it work?
The guides I'm intending to follow are here:

I think I simply used cp -a... (but I'm not 100% sure.)
Edit: then edit fstab and install grub, I guess. I also guess I'm not answering your question; I'm not sure what you're asking.

haha, sorry for not being clear. The question is: can I perform partition alignment on an existing arch installation, rather than having to install from scratch? If so, how?

Just like stqn said.
1. create new (aligned) partitions in the SSD
2. cp -a or rsync (whichever you prefer) from the HD to SSD and update fstab entries
3. install grub in the SSD
4. profit
This is not starting from scratch, as in reinstalling and configuring everything again.

Rookie, thanks. Could you give some details on how to edit fstab and reinstall grub? I can't figure out what I'm supposed to do.

That depends on how you have your fstab, if you use uuid use blkid to find the uuid's of the partition on the ssd and update fstab accordingly.
As for installing grub check the wiki (which might have too much info for what you want to do) and google on how to reinstall grub _after_ installing windows, the procedure is exactly the same. Just in case keep the data on your "old" disk safe in case things don't go smoothly.

This can be marked as solved: I wasted too many hours trying to fix this, then just decided to cut my losses and reinstall. I had all the config files handy on the other hard drive so it didn't take me too long to get back to my old setup. Thanks for your help.
