I tried to update my discourse community, via UI.  
up gradation failed, so I got to know that i can rebuild app and that will restore the discourse.!

but,

my base OS is centos 6.6 (EC2 instance), and there docker version 1.8.x is not supported. (OS updating is a pain..!)  
but discourse says i must update the docker in order to rebuild discourse app.

This is highly frustrating..!  
is there a way out of it ??
