Cyms ending blooming, now what?

[Orquiadicto]

Two of my cyms are allmost through blooming. I guess tomorrow the last flowers will fall off. When this happens, I will cut the spike and I'm planning on repotting them, since I don't know how long they have been in their pots and I've no idea on how the roots are (I guess fine because the plants look very healthy).
After repotting I'll put them on the balcony since the sun isn't so hot anymore here in Barcelona.
Beside this, is there anything else I should do in order to make them feel good and rebloom some day?
Thanks to you all for your great help.
