Question Changing Window header for larger opening?

I am replacing (or attempting to) a 48" window on an exterior load bearing wall with a larger 72" window. I realize I will need a longer header and I will use the same 6x12 timber as what is there only longer of course. My question is, how will I support the load while expanding the opening and changing the header?

Im thinking I could "post supports" on the floor joist above , away from the opening? while I do the work?
Does that sound right?
lol I don't want the house falling on my head.

Is this usual framed construction?? I ask because i am not used to seeing a 6x12 timer header. Headers are usually two 2x pieces of framing lumber nailed together with a 1/2 spacer to make it 3 1/2 for a 2x4 wall. A 6x12 indicates you have 2x6 walls??? If you have stick framing ceiling joist or trusses, you can build temporary 2x4 supports just inside the opening, while you enlarge the opening. Once the opening is secured with the new header, remove the temp. If this is a post/beam house, not sure what to suggest.
