Especially when you pot "out of season" - when it's not producing new roots right away, it pays to be gentle, disturb what it does have as little as possible.

It's looking good for now, though a repot in a year or so is probably going to be in the works when it puts out new growth. The best roots had circled the rim of the old pot so I couldn't get the oldest canes against the back of the new one, too many roots in the way. Also, the 2 directions of growth are going about 60 degrees from each other, so they are both less than an inch from the edge of the new pot. At least they have some elbow room now and we'll see how it responds!

This was all done two days before a nine day holiday trip. The buds were still in the fully enclosed sheath on the day of the trip.
When I got home, this orchid was not only in spike .... but was also opening its two flowers. Half opened on that night I got home.
This suggests that some orchids can keep functioning nicely if they're kept in suitable environments even if significantly disturbed. I wouldn't recommend doing what I did just for fun though. I just did it as it's my procedure I follow for my purchased orchids.
I believe that if lots of mainstream orchids receives what they need (water, warmth, adequate light, oxygen to the roots, some nutrients etc), then they can just keep growing nicely without issue. The same applies for an orchid growing in degraded media or water-logged media getting transferred to suitable fresh media. An improvement in health and growing activity can be expected if the other growing requirements are good.

I see what you mean! From my most recent experiences I have figured out that I should use my (limited) instincts and if I think something is off I should try and remedy that. The plants that I have repotted haven't had any major setbacks, it's the ones that were supposedly in good shape already that I didn't do anything with that I have had issues with. Now that I know what is in each pot for sure as far as medium and roots I can give the best care and not be guessing about it. Now I cringe when I see advice to not repot when in bloom/spike, especially if it is pretty obvious it's needed!
