Bear in mind that End of Life doesn't mean it will stop working. After that point though, the level of support you'll get on such a device will be fairly significantly decreased; it wouldn't be replaced under warranty, if it failed, Meraki Support would max. provide best efforts assistance with it, and there's no guarantee of any fixes in firmware - e.g. for bugs and/or security issues. As Karsten pointed out though, AP licences are not model specific, so most customers simply take the old one off the wall and buy a newer model in its place and nothing is else needed, until that license itself needs renewing.
