[xwiki-devs] Questions about migration path when documents or macros are renamed

Hi! I have two jira issues that I need to fix for 5.3: * http://jira.xwiki.org/browse/XWIKI-9558 - Rename {{workspaces /}} gadget to {{wikis /}} * http://jira.xwiki.org/browse/XWIKI-9491 - Rename "WorkspaceInformationPanel" to "WikiInformationPanel" The implementation is very trivial. In both cases I just rename a document, and in one case I only change the field "name" of the WikiMacro. But how do we handle upgrade? A: If someone has used the {{workspaces /}} macro in her content, she will not see the expected result anymore. B: If WorkspaceInformationPanel is used in a layout, should we automatically update this layout to use WikiInformationPanel? Do we consider we should let the user fix this issues herself, or should we provide an automatic solution to that? If so, how could we do? Thanks for your help, Louis-Marie.
