In case you didn't do any customizations, it's perfectly safe to replace. If you did customize, you can keep your own configs, or do a merge with the new ones.
All in all, yes, it is ok that you opted to replace. I think that was the proper choice.
It would be awesome if someone confirmed/refuted what I have said here though...
Well, I have just gone through the updates and dealt with the Grub alternatives as you suggest. Thankfully everything has turned out OK at a subsequent start-up.
