Clean Up Jira and Confluence Attachments Before Atlassian Cloud Migration

16th June, 20264 Min Read

Since the announcement of the Atlassian Data Center end-of-life, organizations have started planning their migration to the cloud. However, it’s not a simple copy-and-paste job.

Over time, your Jira and Confluence instances accumulate years of attachments. These might include screenshots, log files, ZIP files, duplicate uploads, and other items nobody remembers uploading.

You might not even realize these files exist until migration begins and the bloat starts causing delays.

And if you're opting for the Atlassian Cloud Standard plan, you have 250 GB of storage that you probably don't want to waste on unnecessary files.

That’s why, before you pack your bags, you need to understand what’s worth carrying. Which files are required, which are duplicates, and which can be left behind?

This is where attachment scanning becomes useful.

The Hidden Cost of Attachments in Jira and Confluence

Attachments are easy to ignore in Data Center environments.

You can upload items without a second thought, as storage feels local and expandable.

The problem usually surfaces during migration planning, when you need to understand the true size of your Jira and Confluence environments. That’s when the real challenges begin:

Increased Atlassian Costs

Atlassian Cloud pricing is primarily based on the number of users you have.

But storage also plays a role. Atlassian Cloud Free and Standard plans include storage limits of 2 GB and 250 GB, respectively. If you want more storage, you have to opt for the Premium and Enterprise plans, both of which offer unlimited storage.

However, the Enterprise plan costs more than double the Standard plan.

Would you pay double the price for a premium plan just because your DC instances are bloated with unwanted files?

Slower Migration

Even if storage limits or cost aren’t the deciding factors for you, oversized instances can create other problems.

Large attachment volumes can increase migration payload size and extend migration windows. The preparation and validation cycles will be slower.

How Attachment Scanning Solves the Problem

All of the above problems become easier to solve when you know exactly what exists inside your Jira and Confluence instances. That’s what the attachment scanning feature in the miniOrange DC to Cloud Pre-Migration Cleanup PII Scanner is designed to provide.

Scan Jira and Confluence Attachments at Scale

The DC to Cloud Pre-Migration Cleanup PII Scanner scans attachments across Jira and Confluence content.

It surfaces attachments across Jira and Confluence, along with metadata such as file size, type, and location.

Identify Bulky and Unnecessary Files

Not every attachment has to be moved. You'll likely have many random files someone uploaded years ago that have no relevance today.

Attachment scanning helps you identify such attachments. It gives you an overview of file names, types, sizes, and the exact locations. You can sort them by largest to understand what’s inflating space and see if you even need them now.

For instance, you might find heavy logs or zips that are eating a lot of space but have no relevance today.

Without scanning, those files often remain hidden and get migrated along with everything else.

Reduce Migration Bulk Before You Move

Once you get visibility into all the files, you can remove the ones you don’t need and reduce the size of your environment.

That creates several practical advantages. You can:

  • Optimize your cloud storage footprint
  • Reduce migration bulk
  • Improve operational hygiene

This is especially helpful if you’re targeting Atlassian Cloud Standard but exceeding the storage limits due to junk files.

After all, migration isn’t just about moving data. It’s about moving the right data so you can have a clean start.

Build a Cleaner Jira and Confluence Cloud Environment with miniOrange

Cloud migration gives you a reset opportunity.

You can either migrate your existing clutter or use the migration process to improve your environment.

The miniOrange DC to Cloud Pre-Migration Cleanup PII Scanner supports the latter.

Instead of carrying forward years of hidden files, you gain visibility into what your Jira and Confluence instances actually contain.

You can review all files and remove what no longer serves your business.

The result is a cleaner, more manageable Cloud environment.

FAQs

Q. Why should you scan attachments before Atlassian Cloud migration?

You should scan attachments before migration to understand what is consuming storage in your Jira or Confluence Data Center environment. This helps you remove outdated, duplicate, or bulky files and avoid migrating unnecessary data to Cloud.

Q. Can attachment cleanup reduce Atlassian Cloud costs?

Attachment cleanup can help optimize your Cloud storage footprint, especially for organizations planning to use Atlassian Cloud Standard plans where storage considerations are relevant.

Q. Can attachment scanning improve migration performance?

Yes. Reducing unnecessary attachments before migration can lower the overall migration payload size, which may help simplify migration preparation, validation, and environment cleanup activities.
