Proper install method coming from TomatoUSB to LEDE (R7000)

I did not see anything written in the quick-start guide about migrating from a non-factory firmware such as TomatoUSB to LEDE. Is there any issue simply updating from TomatoUSB's Admin>Upgrade section? I am assuming one should check the "After flashing, erase all data in NVRAM memory" button from within Tomato.

Thanks for any info or links.

Your current 3rd party firmware probably has some documention to revert back to the original vendor firmware, use that approach and then install LEDE from the OEM firmware.

While it might be possible to switch between different 3rd party firmware directly, doing so isn't tested and might fail badly, depending on the particular device and firmware (if said alternative firmware replaced the bootloader or changed the expected OEM mtd partitioning).

Solid advice. Thank you for the quick reply.

LEDE DOES NOT SUPPORT WIFI FOR THE R7000 DUE TO BROADCOMM NOT RELEASING OPEN SOURCE DRIVERS!!!
