Zulip runs on-premises or in the cloud, and integrates with the rest of Atlassian's products. The following describes some typical steps for migrating from Atlassian's HipChat or Stride to Zulip.
Do a trial of Zulip
Stop by the Zulip community server to see what an active Zulip organization looks like. The Zulip community server has around 10,000 users with several hundred weekly actives.
Try to get at least a few very busy people to take a look at topic-based threads on the community server and/or read Why Zulip. Zulip has a unique threading model that makes everybody more productive, but those in meetings all day are often the first people to "get it" and be strong advocates for Zulip internally.
A user experience trial of a team chat tool like Zulip works best if you have a team spend a week using it as their primary work communication tool; this allows the trial group to get familiar with the tool (and with Zulip, experience the magic of topics).
Import your HipChat data
You can export from HipChat or Stride, and import into Zulip Cloud or Zulip on-premise. Instructions are available here.
If you're importing into Zulip Cloud, we recommend doing a test import with us a few days before, and then scheduling a migration date to make sure there is as little interruption in service as possible. The import can take anywhere from a few seconds to several hours depending on how much data you have.
Set up third-party integrations
Zulip has over 100 native integrations, and hundreds more through Zapier, Hubot, and IFTTT.
Read our guides
You may also want to send out material like Why Zulip, the tour on the Zulip homepage, or our guide to streams and topics to users being migrated, so that everyone gets a running start with Zulip's thread-based chat model.
Decide on a payment plan
See zulipchat.com/plans for Cloud pricing, or email firstname.lastname@example.org for on-premise support options. We also offer affordable paid installation help that includes installing and configuring Zulip.
