Transfering Viber from Windows phone 8.1 to windows phone 10

[Windows Central Question]

Hello,

How can I Transfer my viber conversations from Lumia 630 to Lumia 550?
Viber on windows phones doesn t have backup option, and whole phone backup on Windows phone 8.1 is not supported anymore.
Is there any way to backup my lumia 630 and to restore it on lumia 550?

Thanks

I don't think that's possible any longer.
