Narrative:
ECAM: cab pressure system 2 fail at FL350 followed by multiple momentary transitional ECAM's. As a precaution due to fluctuations while automated system transfer occurred we descended to FL250. Contacted maintenance and dispatch and obtained modifications to fuel burn at lower altitude (FL310) and asked maintenance about any history and/or input. None noted so I decided to continue after any/all CRM input.automated system transfer is slow causing momentary transitional ECAM's. Following these momentary ECAM's can cause unnecessary and potentially hazardous distractions and/or complications (following the wrong rabbit down the wrong hole). Update software. Increase training time concerning ECAM compliance vs system knowledge and/or aircraft anomalies. There are transitional ecams that can lead to additional degradation of systems if reacting immediately. I count to three before reacting. It allows me to asses more accurately.
