It's probably a good idea to go through intermediate version for the upgrade. For example, 1.5 -> 1.7 -> 1.9 -> 1.11 -> 1.13. You may be able to make bigger jumps, but going two versions up should always be safe.
You should never need to do this -- upgrading directly from any previous MediaWiki version to the latest is the recommended process and should always work unless something's broken.
I just did a quick test upgrading a fresh 1.5 branch installation to 1.14 branch, and the update went flawlessly.
That may be true by 1.5, but I had a set of 1.3.x installations that I tested some upgrades with to the then-current level 2 years ago and it barfed and died repeatedly and consistently. I asked here and was told to do incremental one-step upgrades.
