Replacing the JIRA issue macro across an entire wiki

[Bill Franz]

A bit of a special case here but maybe others have come across a similar scenario. We're going to be in the middle of a migration of our JIRA and Confluence systems soon, with JIRA moving significantly earlier than Confluence. This will break all JIRA issue macros on our Confluence pages, and I have reached out to the JIRA admins of the new system. We will not be allowed to create an application link from our current Confluence to the new JIRA system. 

So this will leave our Confluence environment with a lot of broken JIRA issue macros. Are there any options to bulk update something like this? Or perhaps is my best option to somehow disable/turn off all JIRA issue macros? Even disabling them may not be viable since even if the macro is disabled, there will likely still be disabled macro warnings on the pages themselves.
