Phpfiwa conversion from v8.4.0

Hi

I am building a new system on a Pi3. Following Glyn’s suggestion I used the emonSD-03may16 image as a starting point.

I installed backup on my old system and after a few hiccups with file paths I successfully exported from 8.4 and imported into low-write 9.7.2. Everything was OK but I noticed I had no phpfiwa directory. Reading on I see the suggestion is to convert to phpfina.

I installed usefulscripts and tried phpfiwa_to_phpfina.php but got the following errors:-

[email protected] /var/www/emoncms/usefulscripts/convertdata $ sudo php phpfito_phpfina.php

Is your setup a standard emonpi or emonbase? (y/n): y

Can't connect to redis at : , it may be that redis-server is not installed or started see readme for redis installation

What is the best way to proceed?
