It is possible, but impracticle.  The reason being is that the new PS/2
line now loads into its parameter tables the kind of drives that are attached
when the system boots.  If you boot with a 5.25" floppy and then change it
to a 3.5" floppy, then the system will still think that it is 5.25".

Just do a DISKCOPY A: A: for the 3.5" to 3.5" copies.  This still doesn't
fix a copy or xcopy problem.  In this case, the cure is to use PC-DOS 3.21,
or over, and assign a logical drive to A:.  Do it by adding the following
to your CONFIG.SYS file:

	DEVICE=[d:][path]DRIVER.SYS /D:0

If you have a hard drive attached to your system and the DEVICE comes before
any VDISK entry, then the logical drive will become D:.  If there isn't
a hard drive, then the logical drive will become C:.

This will allow you to copy files from A: to C: (or D:) without any trouble,
except of course for the fact that you will have to swap diskettes).
