Now I want to move Alfresco to new server Centos 7.0 64 bit , with mariadb-5.5.41 . What should I do ?
I followed article here http://docs.alfresco.com/4.1/concepts/migrating-servers.html but it didn't work.
I tried:
1. Stop Alfresco on old server
2. copy entire /opt/alfresco-5.0.b folder from old server to new server
3. dump and import alfresco mysql database from old server to new server
4. Change ip address of alfresco.host , share.host , db.host in alfresco-global.properties to new server ip address
When I start Alfresco and try login http://192.168.7.20:8080/share , it says "Your authentication details have not been recognized or Alfresco may not be available at this time."

Thanks for your help.

I think the reason because Alfresco cannot connect to mariadb, after install a fresh Alfresco on new server i figured out that there is no table created in alfresco database.
I download mariadb-java-client-1.1.8.jar and put it in /opt/alfresco-5.0.b/tomcat/lib , how I edit db.driver & db.url in alfresco-global.properties to make it work ?

I tried again with new server Centos 6.4 64 bit , MySQL 5.1.67 successfully.
