Controlling client connectivity during access point upgrades

A method includes obtaining client information from a set of access points. The client information indicates client devices detected by each access point in the set of access points. In some implementations, the method includes grouping the set of access points into a plurality of access point groups based on the client information. The grouping allows each client device to associate with an access point from at least two different access point groups. The method includes, for a first access point group of the plurality of access point groups, migrating the client devices associated with access points in the first access point group to access points in a second access point group of the plurality of access point groups. In some implementations, the method includes configuring the access points in the first access point group while maintaining configuration of the access points in the second access point group.
