Editing running journey email to reference the new Content Block

Question

My Journey email is currently referencing a content block and the HTML code has below ampScript

Example :

%%=ContentBlockbyKey(“Old_Content_Block”)=%%

Now I want to change the above code to reference new Content Block instead of the old block, Example:

%%=ContentBlockbyKey(“New_Content_Block”)=%%

So if I make the changes like this in the existing code, will the journey send old or new content after making the changes. Does it not break the journey??

See Salesforce's documentation on this.

If you're updating AMPscript, the documentation states that you need to pause and republish its associated triggered send via Interactions > Triggered Sends > Journey Builder Sends. Once you've updated your email, do the following:

1. Navigate to Interactions > Triggered Emails > Journey Builder Sends, to locate your journey and email.
2. Click 'pause' on the email(s) you wish to update.
3. Re-check the box(es) for the emails you're updating and click on 'Publish Changes'
4. Re-check the box(es) again and click on 'Start/Restart'
