Covering Old Hold in Duct Board (w Pics)

I need to relocate a duct "branch" from the side of a main supply trunk (see before pic) to the end cap of a supply trunk (see after pic) to get it out of the way when I finish my basement.

The main supply trunk is made of duct board. The duct branch is sheet metal.

How do I cover the old hole? Do I simply cut up a piece of ductboard to seal it? then foil tape it?

Also, if I relocate it this way, does the air flow change? Bad, Good, Better? Is this even legal?

duct

you can patch it the way your talking not much eles to do . as far as moveing the 90 if you put it on end you will get more air flow if you got any other grills before the 90 they may loss air . see by comeing off the side you make some air bounce back in duct . by comeing off end it go right throw

i hope this helps
