First make sure all updates and firmware are current before proceeding. Check permissions using Disk Utility, Make a Time Machine backup. (If not, you can make a disk image "clone" backup while started up on Recovery Partition using Disk Utility's Restore function (making absolute sure your target is correct. Before starting a Restore, run the Disk First Aid "repair" on the target drive (your SSD)).

Personally, I always like to have both types of backups completed before a dot update or an upgrade.

Then, I would suggest doing an upgrade to Mavericks. I really can't remember a time where I've had any trouble with this method. However, with the backups, you can always start with a clean install, followed by a migration from your Disk Utility Restore image backup partition.

There's not much downside to the upgrade route, since you always have the option of a clean install if you actually do run into issues.

When installation completes, the Recovery Partition should have also been upgraded. I've been describing a typical Lion (10.7) or later upgrade or install, and haven't done a Maverick 10.9 myself. I can't remember anything about it which would change the above, but those who've gone through it already feel very free (and welcome) to correct me.

The only piece of advice I'll give is make sure you have a backup of your system. If something unforeseen goes on and you lose your data, you'll have at least a backup.

The odds of this occurring are remote but its always good to play it safe.

I think with the past few versions of OSX, there's no issues with going the upgrade route.
