As anticipated Red Hat recently announced Red Hat Enterprise Linux version 4 will be end-of-life in about one year from now. See the official announcement at <https://rhn.redhat.com/rhn/errata/details/Details.do?eid=10950>.
While the 7 year life span of RHEL releases was known in February of 2005 when RHEL4 was first released, I'm sure this announcement was a wakeup call for many customers. If you're running RHEL4 now, what is your migration strategy over the next year? Will you be moving those applications to RHEL5 or RHEL6? Or, do you plan on purchasing Extended Life Cycle Support to delay the need to migrate? Is there anything Red Hat can do to make the transition easier?
I think this is a great opportunity to share your plans and strategies and to learn what other customers are doing. I look forward to hearing your plans, strategies, and questions!
