How we can adjust the pink color layers (shapefiles) into the black highlighted bold layer (shapefile)?

[NasirFarid]

Hello Everyone
I want to add a layer (shapefile) into another shapefile, is there any method to do it.
I already tried spatial adjustment but too tough to do because it not properly going inside, tried others tools too.
Attached is the picture of the shapefiles.
Thank you in advance for your precious time.

Copy > Paste

or 

<CTRL C>  then  <CTRL V>

then use the reshape tool to adjust it to match what you want

Copy paste will not work here. I want the boundary inside the black highlighted one upto best level fit into it.

What your probably looking at is a layer that was either drawn poorly or based off a different projection or different criteria.

Old and new.  You best result is most likely going to be to paste it in and take the time to edge match it as best you can.

There really is not tool that is going to automatically fix this.

it really is a very small area and the areas are off are not huge.

This is 15 to 20 minutes worth of work.  I would just do it manually.
