I am performing AEM 6.4 to 6.5 migration, the tags have been copied to new location /content/cq:tags and old location /etc/tags have been deleted and content pages are re-installed. Post migration i can see the tag property ["currentPageTag"] is coming into the page nodes which is absolutely fine and my old tags are retained in nodes.
Issue: the tag values stored in the nodes as property["currentPageTag"] are not coming/displaying in page properties under current Page Tag section, its coming blank so anyone will have an impression that this page doesn't have any tags associated and if we select any tag from tag picker it overwrites the previous value of tag stored in page node as a property.
Any guess how to display the older tag values in page properties?
Problem was after successful migration of tags the corresponding value of tag saved in page nodes was not displaying on page properties because the corresponding tag and its path was not available in cq:tags, once we rectified with the tags package its started showing up tag value on page properties.
