To keep service interruptions as short as possible, the idea is to = set up a streaming replication from the SUSE server to be replaced to a = temporary Red Hat server and then replace that SUSE server with the = newly setup Red Hat server. My idea is to set up a streaming replication for this. But this of = course only works if the data files would be binary compatible. So, I wonder, if this is possible. We have a lot of databases, some of = them need to be highly available and some are large too. Are there any obstacles that definitely make that a no-go? Do I risk = corruption? It's both Linux, just a different distribution. Cheers, Paul=
