A method is provided for determining whether the immediate state of a telecommunications switch (110) is adequate for a software upgrade or retrofit. A report stream of text messages relating to the state of, and events occurring on, the telecommunications switch is received (200) by a server (102). Predetermined messages are detected in the report stream, including messages indicating hardware errors, alarms and other errors (202). The predetermined messages have a numerical value associated therewith (204). The numerical value reflects a probability of failure of a retrofit if the message is detected. As the predetermined messages are detected, their numerical values are accumulated into an accumulated value (206). If the accumulated value exceeds a threshold, the switch is not fit for the retrofit (210, 211). The time spent receiving the report stream is determined and compared against an expected time (216). If the time spent receiving the report stream does not exceed an expected time, then a determination regarding suitability for upgrade may not be reliable (218, 226). A visual portion (300, 400, 500, 600, 700) of a user interface on a client (104) is updated to reflect whether the switch is in an adequate state for a software upgrade. Hierarchical views of a user interface permit a user to view a failing subsystem, failure type, and associated detected messages in an organized manner.
