Hello, there's no straight forward procedure migrating configuration between different router models, i.e. backup C7 settings and restore them on AX20. So I would use for example notepad to copy the C7 settings and then paste them to AX20 accordingly. Or you could use WebUI interface of C7 on one PC while on another one (locally connected to AX20 only) to transfer them appropriately. Usually for smart home devices would be enough to make the AX20's Wi-Fi settings the same as in C7 router so they can re-connect with AX20 automatically.
