The command cmk --convert-rrds (2.3) / cmk-convert-rrds (2.4+) can be used to migrate recorded performance data from the Nagios to the CMC format after updating from the raw to a commercial Checkmk edition. Prior to this werk, this command was disfunctional for this use case. After executing the command, the Checkmk UI displayed metrics with titles that consisted of a single letter only (next to the correct metrics).
