1 Migration of a CREAM CE service to another physical host

Added:

>
>

The migration of a CREAM CE to another physical host is possible but at the present time we don't provide tools or facilities for assisting the administrator on such delicate operation. The main strong requirement for allowing the migration is: the new host MUST have the same hostname and IP address as the old one. If so, the steps to follow are:

drain the batch queues
install the CREAM CE in the new host by using the same software version and YAIM configuration as on the old host
copy the following files and directories from the old host to the new one: /etc/glite-ce-cream/cream-config.xml, /etc/blah.config, /etc/my.cnf, /var/cream_sandbox, /var/log/cream, /var/lib/mysql/
if the CREAM ES was installed, please copy even the following further files: /etc/glite-ce-cream-es/cream-config.xml, /var/cream_es_sandbox, /var/log/cream_es
