Regarding migration from NCC to Nano wallet

DaisuK ()
I am in trouble that the notice "A wallet with the same name is already loaded!" has been displayed when I try to migrate from NCC to Nano wallet and to import the ".json" file exported by NCC to Nano wallet. Meanwhile, before trying to import the file, I created a Simple wallet with the same Wallet name and Password which are used for NCC . I think this may cause the problem but I don't know how to solve this.
I would appreciate it if some one would advise me how to deal with this.
