Export & Import of SLD with hostname change

Hi,

I have already gone through few discussion on the forum about standard export & import of the data from SLD during migration.

In our case.

Older dev box has hostname: XYZ

New dev box  has hostname: XYZ12

Now with import of technical system from older (XYZ) to the newer system (XYZ12) host name of these TS points to older dev box (XYZ) but not the new one I.E(XYZ12)

The older dev box will stopped at some point of time.

What are the options or solutions insight so that these TS points to new host not the old one?

Appreciate your inputs.

Thanks in advance.

Regards,
