Combining two ember apps

I am currently using ember 1.13. I have two apps which use emberjs. Now I am thinking of integrating these two apps by creating a new route in the first app and display specific route of the second app. Many suggested to use ember-engines,but they need ember 2.10 or higher.Since my application mostly depends on IE 8,I cannot migrate from ember 1.x.

So what should I do? Thanks in advance!!

Cheers!!!

IE8 support was dropped by Microsoft on January 12, 2016 but I think that if you still need to support it you can switch to a more modern Ember version that supports Fastboot (and engines). See also:
