I moved our neighborhood Yahoogroup of more than 900 members to groups.io, and paid for a subscription so I could direct add the members. I¡¯ve found the transition so far pretty painless.
?
For the members¡¯ emails, I downloaded from Yahoogroups the list of members as a csv, which I then saved as an Excel spreadsheet. I just copied and pasted the email addresses from the spreadsheet into groups.io with no problem. I did them in batches of 200 or so, and after the first 400 there was a delay but the adds were accepted pretty quickly (apparently approved by the groups.io moderators) and I had no problem with the rest.
?
I also downloaded the database of member info from Yahoogroups as a csv, saved as an Excel spreadsheet, then created a database structure on groups.io with the same number of columns and same column titles as we had used in Yahoogroups, and had no problem importing into groups.io from the spreadsheet.
?
For the 80+ Word docx files, I had saved them from Yahoogroups onto my hard drive, and those I uploaded to a folder in the groups.io Files section manually, one at a time.
?
I also created a subgroup for our board of directors, and followed the same procedure as above (in Yahoogroups we had had a separate group for the board).
?
The last challenge, which I haven¡¯t tackled yet, is the message archives. I have downloaded them from Yahoogroups, but not yet tried to get them onto groups.io.
