We need to convert a lots of IAPs to CAP mode, then will works with a mobility controller.
We have 2 type of IAPs, 207s and 275s.
IAP-207 conversions works correctly, but have a lot of issues with the 275s. Based on the experience so far, it is a continuous phenomenon that some members of the cluster do not convert. The problem is present in smaller (2-3 AP) and larger (15-20 AP) cluster sizes.Viewing the log file displays the following error messages on that APs:

What can be caused these type of errors?
The error is annoying because it is time-consuming after the conversion to identify which AP has not been converted from many. (have to do thousands of pieces)
The internet connection type is leased line, it's stable, haven't got any problems.
Thanks!
