Unfortunately, I'm afraid you don't have a choice. These 2 coins have different IDs, so the odds will not follow.
On the other hand, to save a little time, you can activate options of the symmetry function, in particular the recovery of the dimensions of the original (which you have certainly already done !!). View image
Personally, when I have a problem with a drawing, I squizz it directly... It's not a very Catholic solution but basically, I register my MEP in .dwg and I work on Autocad... The fact that all the ribs follow from the MEP to the assembly can be very good, but sometimes... How heavy (not to say s****) !!!
PS: you can copy and paste too, it works both ways, from Solidworks to Autocad and from Autocad to Solidworks.
if a maximum of dimensions come from the 3D model (by the "model objects" function) you can make a copy of your MEP and change the part in it (by file / open / references)
If your symmetry is well done and your symmetrical piece takes up the elements of the original (as Benoit.LF said), you shouldn't have too much work.
I did the test of going back to the original drawing by re-orienting the reference to the symmetrical part, and it doesn't help at all (at least for the dimensions from the 3D)! Despite the link between the original part and the symmetry part (by the symmetry options), all the ribs become wobbly! It's a mess though!
In tools there is therefore replace the model, try, and you will see that for this case, it's almost perfect =)
I'm still in 2013, I didn't know about this position.
it may have been made for this case...

It all depends on the number and type of dimensions imported from the model. If a majority of them come from 3D, all you have to do is import them and position them in the new MEP.
The dimensions created in the plan always lose their references, but they can be linked more or less easily.
It limits a bit the manipulation of dimensions and avoids starting the plane from scratch, but does not make a perfect symmetry of the plane, far from it.
This is a black spot of this software.
@Bart:
Can you give us an image of a raw plan from this new function, so that we can judge the effectiveness?
