Most effective method I consider is copying the new sky texture in any sector to clipboard and press CTRL + ENTER on said sky. That will ensure all properties (shade/pal) get transferred. You might have to do it a few times in places the sky isn't fully connected.
ALT + C will replace all textures currently pointed at with clipboard copy, but doesn't transfer any properties over.
Hope that helps.
