Open the channel browser. Sort by "last activity" and identify the 10-20 channels actually in use. Every dormant channel is dead weight you won't recreate in Discord.
List active integrations too - GitHub, Linear, Sentry, Calendly, bot workflows. Most have Discord equivalents but you'll need to reconnect each.
In Discord, click the + in the left sidebar. Choose "Create My Own" → "For a club or community". Name the server after your company or community.
Discord uses Categories and Channels instead of Slack's flat channel list. Use Categories to group related channels: #General, #Engineering, #Support, etc.
Recreate your active Slack channels. Map Slack user groups to Discord roles:
@admin → Admin role
@moderators → Moderator role
@team → Team role
@contributors → Contributor role
(everyone) → @everyone (default)Set channel permissions per role. Discord's permissions are more granular than Slack's - take 15 minutes to model them properly.
Generate a permanent invite link (Server Settings → Invites). Post it in Slack's #general and pin it. Email it to core members who don't check Slack.
For communities, consider requiring members to accept rules (Discord's Community feature) before they can post. Reduces spam dramatically.
Reconnect each active integration:
GitHub - use Discord's GitHub integration or a webhook. Post PRs/issues to a #github channel.
Linear/Jira - webhook into #engineering.
Sentry - alerts to #errors.
Calendars - community events via Discord's Events feature.
Discord has fewer first-party integrations than Slack. For anything custom, use webhooks.
Discord does not import Slack history. Export Slack as a JSON archive (Workspace Settings → Import/Export) and store it somewhere accessible (Drive, S3).
Pin the most important messages from Slack manually in Discord before turning Slack off - institutional knowledge, SOPs, pinned links.
Discord's default moderation is light - fine for a 20-person team, catastrophic for a 2,000-member community. Set up:
Verification levels - require phone/email verification for new members.
AutoMod - Discord's built-in spam/profanity filter.
Moderation bot - MEE6, Dyno, or Carl-bot for logging, timeouts, and bulk moderation.
Slow mode on busy channels to prevent flooding.
Give 1 week of overlap. After that, demote all members to single-channel guests in Slack (or pause the workspace), and post a pinned message pointing to Discord.
After 30 days of zero Slack activity, downgrade to free or cancel entirely. Keep the JSON archive somewhere retrievable.
Slack threads hang off parent messages. Discord threads are full sub-channels with their own history and members. Plan your thread usage deliberately.
Nothing imports your Slack messages into Discord. Pin what matters manually and keep the Slack export as the archive of record.
With unlimited members and default notifications, even a 200-person server can feel overwhelming. Default new members to muted categories and let them opt in to topics.
Discord is designed for communities, not internal teams. If your workspace is used for deal reviews, HR chats, or sensitive docs, Discord's community-first UI will feel wrong. Slack is the better choice there.
I'll set up your Discord server, map roles and permissions, reconnect your integrations, and run the member migration - so nothing breaks when you switch.
