Repotting deciduous, spring-blooming species

[Angurek]

Hey, everyone.

I have a Lycaste consobrina and an Anguloa cliftonii that are currently in full bloom and continuing the growth of their leads. As this is my first time growing members of this alliance, I was wondering when it would be best to repot. The medium around the roots of both is in need of replacement, but I don't want to stress the plants out since they're doing so well. Should I wait until the flowers fade to repot, or would it be best to wait until the plants are dormant?

Thanks.

Carl - wait until the flowers are spent and the new growth begins.
