Migration from V9.10.1 to V13.10.2 with issues on "/bin/view/WikiManager/" page

Hi,

I have done the migration from V9.10.1 to V13.10.2.
There is some error on the log.
Some of them are explained because some attachments doesn’t exist anymore.
Some errors occurs during the upgrade process the error appear in the log only nothing on the UI.

I can’t display all the wikis for non admin user on the URI “bin/view/WikiManager” (see No entry displayed on WikiManager page for an non admin user with and error notification and log trace)

I have also attached a pic of the result of the “compute update” (URI “bin/admin/XWiki/XWikiPreferences?section=XWiki.Extensions&search=standard+flavor&repo=installed”). This displayed is not clear for me
