Will 1.9 mods work in 1.10?

[matiasb]

As 1.10's release is tomorrow, I was curious to see if anybody knows what mods could work in 1.10, or if any will work at all. 

If not, then, do I have to delete all my mods before upgrading?

Thanks in advance!

Generally part mods and mods that add textures work well between major version changes. Most plugin based mods may also work fine considering there is no major unity version upgrade. Mods that are version locked like Kopernicus and their dependencies don't work as the mod author has chosen for them not to yet. Mods such as EVE and scatterer may or may not work depending on back-end changes (e.g. in 1.9 they introduced a unified camera system for DX11 which broke scatterer). I also have a feeling 1.9 version of texture replacer may also not work due to the new suit picker.

What I would do if I were you is backup your savefile and then run all your 1.9 mods at once on 1.10 after you've tested a stock install, and see if you find issues. If you do, remove the mods you think are most likely to be the problem 2-3 at a time and wait until the issue goes away. The mods that you removed are the ones likely needing an update. 

That's probably a bit oversimplified, but hope that helps.
