I am looking for best practise (or stuff like that) to prepare the upgrage of a Talend platform in High Availability architecture. The HA concern TACs, job server and runtime server. Of course, this upgrade must be perform without of impact (or minimum) on production environment, several jobs are running during working hours and web services are up and running 24 hours a day.
Have you some documents, URL to prepare (or to understand) this kind of migration ?
