Safest way to move Discus to a community tank?

I’ll be moving my big group of 14 discus to a 200 gallon tank stocked with mostly tetras, corydoras, and several geophagus and I was wondering the best way to move them over.

The acclimation part is simple but I’m more worried about the introduction to new pathogens. I will say that I don’t really do much in terms of preventing cross-contamination and will dip my arms into both tanks here or and there or move some BN plecos around but otherwise theres been nothing major.

Whats the best way to move them over while minimizing risk with any possible infections?
