Swapping winters/summers on the same rims: OK?



While I'm sure it would be optimal to have separate rims for winter tires for so many reasons, would I be doing irreparable damage if I swapped tires on the same set of rims used for my summer tires, year after year?
(I'm trying to save $$$ these days, and would like to forgo having to buy separate rims for winter tires.)
Appreciate people's opinions!
