RHEL5/CentOS5 End Of Life

[kazuhisya]

RHEL5 and CentOS5 will end-of-life at the end of March this year (March 31, 2017).

• Red Hat Enterprise Linux Life Cycle - Red Hat Customer Portal
  • Life-cycle Dates
• FAQ/General - CentOS Wiki
  • 20. What is the support ''end of life'' for each CentOS release?

So, when that day comes, I will delete patches and fixes that exist only for el5.
Or should I maintain patches and fixes for el5?
