I'm DMing a party of five and they're going after Yeenoghu as the campaign's final boss. I've looked online and haven't found any 5e stats for the Demon Lords, but I did find this for a 3.5e Yeenoghu. I've read the official conversion reference, but that's more for player characters and might not apply to extremely powerful beings like this.

I want to create a stat block that would be just as challenging for a 20th-level 5e party (with some magic items and divine blessings) as the block linked above would be for a geared-up 20th-level 3.5e party, but I haven't played 3.5e so I don't have a sense of what characters are capable of there. Obviously a +54 to hit and 45 AC is ridiculous in 5e, but using the quick conversion guide in this question, the resulting Yeenoghu seems too weak for someone with a power level similar to that of the gods.

Are there any official guides for converting very high level stat blocks between editions? Or just a published 5e stat block for Yeenoghu? According to this question, Fraz-Urb'luu has one, but I don't own the relevant book to check it for other Demon Lords.

A statblock for Yeenoghu is included in Appendix D of the Out of the Abyss campaign book.

You may find this statblock a bit weaker than you prefer; it's certainly not at "a power level similar to that of the gods." (Demon Lords, aren't, generally, nearly as powerful as the gods.) I'd recommend simulating a battle with your party and seeing if it's as challenging as you want it to be, and making some adjustments based on what you find.

Start from scratch

20th level 3.5e characters have near godlike powers. For example, a +30 or more attack bonus would not be unusual: that would hit AC 40 about half the time.

20th level 5e characters are not in the same league. An attack bonus of more than +11 would require magic or a score over 20. This would need a critical to hit an AC 40.

Look at 5e stat blocks for CR 20+ and take your guidance from those. Use the 3.5e stat blocks to decide the feel of your demon lord.
