Win 7 Thunderbird (V64.04.0 32 Bit), transfer emails/contacts to Win 10 + Thunderbird

Salarboy

I have an old Win 7 laptop running Thunderbird (V64.04.0 32 Bit). I need to transfer emails and contacts to my new Win 10 with Thunderbird. I have tried to do this as from FAQ, eg 1) downloaded "importexporttools-3.3.0-sm+tb" which will not run nor can I find a way to activate it from T/B; 2) installed and restarted T/B with import / export add on "Thunderbook" but there is no visibility of how to start the export facility. Any advice on how to transfer emails and contacts in a simple manner would be appreciated
