Replace tag in the reference pages
I have two tags 'wknd:old' and 'wknd:new'. 'wknd:old 'tag has 288 page references
And 288 pages have old tags as well few other tag values associated to them.
Suppose
/content/wknd/xyz is a page and it has tags=[wknd:industrial; wknd:compressors, wknd:old].
Here my point is to replace the old tag with the new tag on all pages without overriding existing tags just like below.
/content/wknd/xyz is a page and it has tags=[wknd:industrial; wknd:compressors, wknd:new]
Merging the old tag with a new tag isn't helping here, page reference still pointing to the old tag.
Can anyone provide the curl command to replace tag values on multiple pages.
