WRN1:7561 ADMT could not migrate some properties for this object type(computer)due to schema mismach

[VedaGentech]

Hi Frineds,

I am doing user and computer migration from one forest to another forest. I have setup trust between two. Setup dns things and installed ADMT 3.2 version on server 2016.

My source domain 2012 r2 and target domain is 2016. 
I am able to migrate users from source to target domain without any issue. But not able to migrate computers. While migrating computers I am getting below warning message. Computer is transferring from source domain to target. My source domain has exchange on it but my target domain does not has it. 

Can somebody faced similar issue? Can somebody help?

WRN1:7561 ADMT could not migrate some properties for this object type (computer) due to schema mismatches.  Please refer to the Schema Section in the migration log for a complete listing.  The Schema Section will be available once object migration is complete.
