If you use the IPMI Sensors check and configured levels via the Set lower and upper levels for numerical sensors option in the IPMI Sensors rule on Checkmk 2.4, these levels were not migrated correctly during the update to 2.5.

This causes the IPMI Sensors check to crash on affected hosts with:

TypeError (tuple indices must be integers or slices, not str)

During the update, or when opening the rule in the UI, you may also see a validation error containing:

Invalid datatype of value: <class 'tuple'>

Affected rules are now migrated correctly during the update.
