Confluence Cloud to Cloud migration. Testing without a sanbox.

[aggelos_kanarelis]

Hello all

We are preparing for a Confluence cloud to cloud migration. Our main problem is that we do not have a premium subscription and as such we do not have a sandbox to test. 

We are looking for recommendations from people who have performed similar migrations with similar constraints. How did you do it? How did you tested? What were the challenges and how did you overcome them?

One more question would be whether it is best to migrate space by space or all at once?

thank you all

Hello @aggelos_kanarelis 

Welcome to the Atlassian community.

Will you be migrating to a new, empty site? If so you can set up a new trial subscription for testing the migration.

Whether to migrate space by space or all at once depends on a few factors such as how much information is being migrated and your tolerance for downtime.

@Trudy Claspill thank you for replying. Let me clarify a couple of things, which I probably should have included in my original post.

We have a jira site and a confluence site. The idea is to add confluence to the jira site (which of course has a lot of data)and migrate the confluence site there.

We are under the impression that with a new test site we won't be able to test all the integrations properly, is that not the case?

Regarding the space by space question, there are about 400 spaces, many of them personal, not all of them with data in them. We estimate about 9GBs of data will have to be migrated. 

What do you mean downtime tolerance? Site by site will have more downtime or all at once will have more downtime? When we say downtime we mean that confluence will not be accessible at all?

What integrations are you trying to test?

Can you confirm for us that you have already reviewed the documentation on the Copy Data feature? I don't want to unnecessarily repeat information you already know.

The data transfer does not require down time in the sense that the source instance is inaccessible. But you will not want your users to be making changes to source data while the transfer to the new production site is in progress.

A test transfer will provide information about how long the process will take so that you can advise your users accordingly when the production transfer occurs.

I can confirm that the documentation page you posted was our first stop when we started discovery. Following apps are currently installed in confluence site:

Analytics for Confluence
Confluence Cloud for Slack
Confluence Power-Up
Embedded Marketplace
Google Drive for Confluence (Official)
Confluence Cloud for Microsoft Teams
Miro Content Hub
Miro Embed for Confluence
Opsgenie Incident Timeline
Opsgenie Incident Timeline EU
PlantUML Diagrams for Confluence
Confluence Trello Power-Up
Slack - Rovo to Slack Connector

Our guess is they would all have to be tested.

Thanks for clarifying about downtime. We have planned for that, but we thought there was something else affecting it as well.
