Will old hard drive work in replacement router without re-install?
-
At some point down the road I will replace my j1900 based router with one that will support AES-NI. No problems there. I have a spare ready to go. I'm in no hurry since the j1900 router still works great.
My question: They are different architectures in many ways. If I swap the hard drive from the j1900 router and put it into the replacement router, will it reconfigure automatically - except for possible interface resetting? Or will I need to do a re-install?

I would reinstall, restore the configuration, and reassign interfaces.

OK. Will do.

If you really want to get fancy you can edit your interface assignments in the config XML before you restore. For example if going from 'em' to 'igb' driver, just find / replace 'em0' with 'igb0' and 'em1' with 'igb1'
That should work even if you have VLAN interfaces and/or LAGG.
You can even test this beforehand by restoring your config to a virtual machine.
