Hey guys I've been on a jailbreaked iOS 5.1.4 for about 18 months and want to upgrade to iOS6 and jailbreak it. Is that even possible? Thanks!...

Impossible, you can upgrade only to 7 and jb

Let's figure out exactly what version of iOS you're on, as there never was a version known as "5.1.4."
If you're on 5.1.1, you could theoretically get to iOS 6 once with an iPhone 4S, if you have the correct SHSH blobs (which for all the jailbreakable versions of iOS 6, isn't a guaranteed proposition).
There's a bug in iOS 5's ramdisk used for restores that will allow a restore to an arbitrary version of iOS (with the correct SHSH blobs), but it only works if you restored (not OTA, nor updated, nor with it installed from the factory) to iOS 5.1.1 (or any other version of iOS 5). You'll need redsn0w's Restore function (Extras -> Even More -> Restore) to pull it off, assuming you meet the necessary criteria.

Can you elaborate a bit more? i just want to confirm with what you are saying.
1) Iphone 4S on 5.1.1, have not been updated to 6.x before, now jailbroken.
2) Valid 5.1.1, 6.0.1, 6.1.3 SHSH created by TinyUmbrella (ifaith said the appticket looks valid but it cannot support)
Do I have what you mentioned "criteria" to get my Iphone 4S to 6.1.3??

Even if you have shsh blobs for iOS 6 for your iphone 4S, it cannot be used at this time

If my understanding of this restore exploit is correct, you hypothetically could get ONE restore to 6.1.3 (with the 7.0.4 baseband), but then would be stuck there or be forced forward to the current Apple release.
However, I do not know if redsn0w is build to function this way. In fact, I don't think it does. Thus, we're left with the normal functionality of the 4S, which is "only the most current signed firmware."
