When I rebedded my lowers, I took them all off, one after another, did the "drill out the deck hole a size or two larger then fill the hole with epoxy and redrill it for the chainplate" thing, then rebedded each with 4200. I don't think it makes any difference if the (relatively flexible) mast is pulled a tad out of column as you loosen one lower shroud, then another, but you could always go around all the lowers loosening each turnbuckle a turn until they are all loose enough to disconnect. And counting the turns as you go would give you an idea where you want them when you put it all together again...
When I replaced the bulkhead to which the upper attaches, I first strung the halyard to the stanchion base near the upper shroud chainplate, then lossened and removed the shroud.

|jackytdunaway||Cool. So it sounds like it is not that hard to do. Thanks for all the input and advice|

In a case such as yours where there is only one chainplate you must use halyards to support the mast. It's either that or just unstep the mast.
What I do is hook up the halyards first. Then disconnect the upper shroud turnbuckle from the chainplate and hook it up temporarily to the toe rail, a midship cleat or something. It can even be lashed on. You don't want to load it up too much, but you don't need much just to hold the mast up. After you temporarily hook the upper back up, go ahead and remove the lower.

|jackytdunaway||i am bumping this back up. i really hope to hear from someone that has done this with a deck stepped mast|

|jackytdunaway||What i am trying to figure out is with a deck stepped mast and only a single chain plate on each side (the upper and lower both go to it) can i take both loose and leave only halyards to supprt the mast (along with the stays) while i rebed the chainplates|

You only "disconnect" them when you are ready and only, as I mentioned, singly or in pairs. One on each side at a time.
Sorry, I thought that was clear.
Since we are only talking about shrouds, not stays here, there is no problem removing both upper shrouds at the same time. Or both Aft lowers. Or the starboard aft lower and the port forward lower.
You get the idea. Whether it's keel stepped or deck stepped, it makes no difference. As long as you have a couple of shrouds on each side holding the mast up, you're OK.
The reason for easing the turnbuckles initially is simply to keep the mast more or less in column when you remove a shroud or two.
I've had both uppers off and been hanging from a bosun's chair from the main halyard with both shrouds coiled and tied to the chair and about 20 lbs of tools while hanging from the main halyard. Lots of times.
Although I usually, as mentioned, only take one of each off and duplicate it twice when making new shrouds.
The point is, if you could take the mast and lay it on saw horses, you could support it in the middle and walk all the way out to the end and it wouldn't break. It's going to bounce like heck, but it's not going to break.
Just like being up the mast on a Freedom or one of those freestanding Hunters. It's disconcerting, but hardly dangerous.
And we aren't even talking about going aloft here. Just replacing chainplates.

Halyards aren't really necessary, but they sure can't hurt. Sometimes, you can hook the shrouds back up temporarily to the rail too. Just don't load em up.
You must be speaking of a keel stepped mast. Certainly a deck stepped mast will have to have something holding it up. On a deck stepped mast are halyards OK while the chainplates are rebed. My upper and lower both go to the same place and i need to rebed but am nervous about taking the shrouds loose

Thanks everyone. I didn't reply sooner since I was out on the boat this weekend. I appreciate all the responses and help.
