Hi, I have two Linux servers both having same Hardware architecture one have ES5 and the other having ES4. Both the servers have same version of PostGres installed (8.3). I want to move all my DBs from ES5 server to ES4 server. I have tried the pg_dump but there are a lot of encoding problems, so can I copy the whole data directory from ES5 server to ES4 server when the PostGres server is not running? Will it be safe?
Thanks
Ehsan
