Updated Teams Command Line Tool - Channel Surf

[Tam Huynh]

(Disclosure: I work for Microsoft, but not as a member of the Microsoft Teams group)

I've released a new version of my Microsoft Teams command line tool which I've called Channel Surf.    The existing version lets you re-create your existing Slack channel structure in Teams and bulk add new Teams channel.  

My new version is now on GitHub (https://github.com/tamhinsf/ChannelSurf/) and now enables you to:

• Archive Slack messages into HTML files and store them in Teams
• Copy Slack file attachments into Teams

Further details are up on my GitHub page. 

How? Slack enables a team owner or admin to download an archive of a their team's history, which Channel Surf scans and then uses in conjunction with the Microsoft Graph API to re-create Slack channels within Microsoft Teams, generate HTML message archive files, and upload these archives and associated file attachments.

It's a work-in-progress - I've only tested this on a couple of small Slack archives. The display of user names, date and time stamps, message formatting, and viewing experience will be improved as I have free time. But for those of you wanting/needing more - there's always the fork and clone buttons to help you get started. 

As a gentle reminder, I'm reliant upon public Microsoft Graph and Teams API's.  The API's needed to perform a true message import aren't yet available: these include impersonating a user, backdating the creation date of a message, and probably a few other things I haven't thought of.

Hopefully for now, some of you will find this useful in your pursuits.

Is there a limit to how many HTML message history files will be created? I noticed in the command prompt for one particular channel that all message history json files were created in Temp but only 18 were uploaded to MS Teams.
