Computer-implemented techniques for controlling virtual machine (VM) porting activities based on dynamically-calculated virtual machine predicate values. Upon receiving a command to port a subject virtual machine from a source virtualization system environment to a target virtualization system environment (wherein the source virtualization system environment and the target virtualization system environment are different), one or more match expressions that describe time of day and resource predicates conditions, under which porting operations of the subject virtual machine are to be carried out are evaluated. Based on observance of the aforementioned time of day and resource predicates, various virtual machine porting operations are either carried out (e.g., when applicable match expressions and / or predicates evaluate to TRUE), or are temporarily suspended (e.g., when the applicable match expressions and / or predicates evaluate to FALSE). Multiple virtual machines can be ported concurrently while observing VM priorities and bandwidth throttling.
