Switch from Gliffy to draw.io in three steps

This page will guide you through your Gliffy migration. We start with a few basic settings and recommendations before we actually perform the switch to draw.io. The guide is sequential, so just go through it step by step. 


1. Prepare


Migrating from Gliffy to draw.io is fairly easy; you can switch with one mouse click. However, we do recommend that you take care of a few things in advance in order to save time and so the converter can run smoothly.




1.1  We highly recommend that you perform the mass import on a test instance first

  • Gliffy diagrams with custom shapes or non-standard formatting may not convert to draw.io diagrams correctly at first. This is fixable, don’t worry, but migration on a test instance is always best (follow Atlassian's instructions to create a test instance from your production instance).
  • If you can’t create a staging environment, copy important diagrams to a created demo space first and perform the migration for this space only.




1.2  Re-index Confluence so all Gliffy diagrams can be found

  • In order to avoid partial or failed conversions, please rebuild the search index (see Atlassian documentation) so the converter can find all Gliffy diagrams later on. 



1.3  Check if you have the latest version of draw.io

  • If you already have a staging environment and have tested draw.io before, please make sure to update draw.io to the latest version before you start the migration.




1.4  Be sure the Gliffy app is installed (mandatory since draw.io version 9.2.1)

  • Gliffy should be installed on your test instance, so that you are able to visually compare the results after the migration.
  • The mandatory Gliffy installation doesn't require you to have a Gliffy license. We actually recommend that you remove the license before carrying out the live migration.




1.5  Do you have full permission to access all Gliffy diagram pages?

  • The administrator that carries out the Gliffy mass import must have write-permission for every Confluence page containing a Gliffy diagram. Otherwise, the mass importer won't be able to save the draw.io diagram to that page.
  • If no such user exists, you will need to temporarily promote a user to administrator status in order to have those permissions during the import.


2. Import Test



2.1 Install the draw.io app

Firstly, access the general configuration area of your Confluence administration panel and install the draw.io app in the Atlassian Marketplace section. After installation, apply the 30-day trial license and select Configuration, which you will find under in the navigation panel under DRAW.IO ADD-ON. Then, click Gliffy import on the draw.io configuration page.

(warning) If you've already purchased draw.io for Confluence Server, use your license key together with your Confluence developer license.





2.2 Import the Gliffy diagrams

Click on the Start Import button to import all of the Gliffy diagrams in your instance. You can also use the option Filter by Spaces to import only the diagrams attached to pages in this specific space (good for a quick test on a demo space). Both the current Gliffy JSON and legacy XML formats are supported.

The duration of the import depends on the number and the complexity of the existing diagrams, and doesn't normally take longer than a few minutes. With just one click, all of your Gliffy diagrams within a Confluence instance can be imported into draw.io.




2.3 Download the report

Wait until the import has finished, then use the link beneath the Gliffy import button to download the report. Use the report to see whether all diagrams were converted successfully, and which diagrams were unable to be imported.


You can additionally watch the import test in our video guide.

3. Live Migration


3.1  Outside of working hours

If the report didn’t show any issues with complex Gliffy diagrams you can perform the conversion on your live instance. We recommend that you perform the conversion outside of your company's normal Confluence usage hours. It is possible during normal working hours, but it's best to carry out the whole operation whilst the minimum number of changes are being made to the relevant pages.

3.2  Remove Gliffy license

The recommendation of removing the Gliffy license is so that users do not start editing Gliffy diagrams while the process is running, effectively making Gliffy diagrams read-only. It is worthwhile communicating with users that you are carrying out the migration, and when you expect to start the process.


3.3  Like to keep the original last page modification date and set custom comments to migrated diagrams?

Although the migration doesn’t change the content of the page, (it only replaces the Gliffy macro with the draw.io version of the diagram) a new version of the page with an actual timestamp is created. Some customers like to keep the original date of the last page modification as to not confuse colleagues who might search for content within a specific time period. You can configure this just by adding the parameter keepDates=1 to the URL, for example:

   https://BASE_URL/admin/drawioConfig.action?keepDates=1


You can also set a custom comment applied to converted diagrams (per default the comment draw.io mass import is set) by adding the parameter pageVersionComment=YourURIEncodedString to the URL of the draw.io admin page:

   https://BASE_URL/admin/drawioConfig.action?pageVersionComment=MyComment

Of course you can combine both parameters, the URL will change as follows:

   https://BASE_URL/admin/drawioConfig.action?pageVersionComment=MyComment&keepDates=1
