Moving toilet drain pipe

Current bathroom has a low ceiling height due to ducts and plumbing. I removed all the ducts but left with the toilet drain from above bathroom. Can this be moved closer to above subfloor? Thereís a joist right in the way so not sure how to move this without impacting structural integrity.

You have two things you need to address.

1) The cast iron sanitary tee would need to be cut out and moved up (replaced with PVC). It looks like that galvanized steel pipe would need to be relocated too. Though if I was redoing the bath, I'd probably replace that galvanized pipe too as most galvanized is nearing the end of its useful life.

2) The joist needs to be cut out and re-structured. Usually adding another perpendicular joist 'header' will handle the load. Others will help with the details.
