How can I find and replace multiple confluence pages Source code

[Monika Rani]

Hi All,

I have migrated my space from the server to the cloud and I am using the ConfiForm App too. After the Migration, my pages are broken

and I found what is the issue with why this error was coming. Actually

The Migrated Pages had the code for a title like this : 

<ac:parameter ac:name="pageTitle">Scheda attrezzaggio macchina</ac:parameter>

But on the cloud It should be like this : 

<ac:parameter ac:name="pageTitle">
<ac:link>
<ri:page ri:content-title="Scheda attrezzaggio macchina" />
</ac:link>
</ac:parameter>

After changing the code, pages are looking perfect.

Is there any way? I can find the old code and replace the new one for all the pages of my space.
