As you know 8086 and 8080/Z80 are different microprocessors
with different instruction sets. Therefore the programs (.COM files)
from CP/M 80 will not execute on the 8086. If the programs are
written in a high level language and you have the sources and the
language's CP/M 86 counterpart exist, then you could
recompile/reinterpret the sources to execute the programs on CP/M 86. 

Data files, however, are compatible enough that you should not need
to modify them.
