Can TRs selected in sequence complete the import against the order?

Hi,

In a scenario when some transport requests need be imported in sequence and the first TR contains several objects with an older version of a particular object whereas a TR that follows later in the sequence contains a newer version of the same object but its a lighter one containing only that object,

if we select the TRs in order and import them together, Can the lighter TR which contains the newer version go first and later be overwritten by the first TR containing the older version ?

Also, in such a case, can the lighter TR which comes late in the sequence be completely imported before the first TR which is heavy?

Thanks in advance,

Prateek
