I think this is an issue that has two sides, and ease of programming and maintaining an automated system is only one of them. If we were a mere ladder with thousands of members, it would be the only one. But since we are, as they say, a roleplaying club, "soft" matters like army cohesion and loyalty should have at least an equal say in finding a solution.
If battles between members of opposing armies can continue to be battles--in extreme cases for years and years--once they become members of the same army, and VPs can be earned by leading the enemy against the own troops under a fellow officer of the same side (even if only in a couple of cases every year), the value of army affiliations becomes somewhat dubious. We could end up questioning the very value of the battle/maneuver distinction--abolishing that one would certainly make maintaining the auto system even simpler!
Moreover, if we make it possible to earn full points for a battle between members of the same army after a transfer, there is a disparity between full points for battles that continue after a transfer and only half points for battles completed before the transfer--since points are halved in transferring.
Now on the other hand, counting battles as maneuvers for *both* sides after a transfer would be a grave injustice to the opposing player who would lose a chance for VP and full points just because his opponent decides to transfer into his own army.
I think the system used hitherto, i.e. after a transfer the transferring officer receives half points and no VP, while his opponent receives full points and full VP, if victorious, while being a tad more complicated on the face of it, has the advantage of complete fairness to both sides. If the system cannot be designed so that it can allow for such cases, it should be possible to enter or correct these games manually. -- And Ernie is right, if it has to be done manually, then it is not the system administrator who should be obliged to remember (though shouldn't it be possible to add a flag to an entry that shows up upon completion of the game?), but rather the players themselves. Likely best that their game should count as maneuver, them being on the same side, but the (non-transferring) opponent should be able to claim VP and full points afterwards.
