Cut the tee out, and point the new tee toward the blue tape.
Then point it out the wall with a Medium 90
If the pipe is 1.5" it should be fairly easy.
If it's 1.25", it will be harder to find pipe and fittings.
If it's over a crawl, you can find a 1.5" pipe or larger to connect to.

Is the drain exposed below the floor?

Terry-
Thanks for your prompt answer, as usual. Yes, it's 1.5".
Followed you great up to "cut the tee out"!
1. What kind of new tee can I use for the replacement?
2. What kind of pipe will I use for the run over?
Export-
Yes, fairly spacious and easy to work in crawl under the bathroom.

The company that I work for still uses this galvanized pipe set up. The vent bar and stack fitting with the shower arm already comes pre-fabed from the shop. Before cutting the tee out try to see if you can spin the tee. Figure out the size of the branch and buy a 2 feet piece of gal pipe. Insert the pipe into the branch get it snug and then turn it clockwise to the desired position. I always encouter this situation when working on rehabs and it never fails.

I'm with Terry- cut the tee and a few inches of pipe top and bottom. Transition the galvanized to new PVC pipe and sani-tee with shielded no-hub couplings. Run new 1.5" PVC properly pitched and turned out to the new stub-out then finish with a trap adapter.

Couple more questions:
1. When I cut out the old cast iron tee from the long vertical run of galvanized drain pipe and replace it with a PVC tee and two no-hub couplings, is there some additional support needed? What?
2. When I run the new horizontal length of PVC and turn it out with a 90 degree fitting, how is that fitting supported behind the wall?
TIA.

Turn the tee and screw a piece of galvanized, or PVC/ABS with a threaded adapter into it. Regardless of how long it has been installed, it will turn. Either use a large pipe wrench, or a piece of pipe screwed into the opening. Drill a hole in the stud and that will support the pipe.
