Any issues with joining cat5e and 6?

[Tazz 316]

joining together 5e and cat6, i have a bunch of cat5e cable that is underground that i need to extend.

5e Direct Burial seems to be out of stock in a pull box, i do not want the wood spool i find it a pain to move around in tight places.

It can be done but as with any underground cable it is not ideal as it becomes a weak spot for potential issues especially if it is not sealed properly from moisture I would definitely recommend either avoiding it or join it at an accessable waterproof junction box on a building wall or fence post for example
