Capsman VS cisco capwap

Hello, is it possible to replace a old WLC cisco 5508 and 1532 Exterior APs by a Mikrotik infrastructure?

Actually we use 2X 5508 HA and 50 X 1532.

If yes, what is the maximum APs supported by capsman

and which gear i should be use?

Thank you

Yes, you can. Capsman should support an unlimited number of Mikrotik AP’s, at least in theory.
As gear, maybe a rackmounted ccr2004 or ccr1009 and any outdoor/indoor mikrotik wireless that suit your needs ?
If you have a scenario involving p2p wireless bridges and redistributing wifi after this links, you can’t control wireless bridges on capsman. Still, you can make the wifi backbone and control the ap’s to the clients from capsman. Ex: if you have a mikrotik board with 3 radios, 1 wifi radio can be used to make the wireless bridge and 2 radios can be controlled by Capsman.
