18		-If you're upgrading from an older version and you use the new Distribution Wizard to upgrade your wiki pages you'll notice that it'll ask you to merge all pages that have been modified between your version and XWiki 4.2. This is because currently the Distribution Wizard doesn't know which version you have and thus asks you to perform the merge manually. This operation may take a long time (up to 20 minutes or so). Thus at the moment if you're upgrading from a previous version we recommend that you Cancel the Distribution Wizard and instead [[Import the new XAR>>platform:AdminGuide.Upgrade]]. This problem is [[reported in this issue>>http://jira.xwiki.org/browse/XWIKI-8252]] and should be fixed in the next release.

22		-If you are migrating from an earlier version than 4.0, and your database contains statistics collected using a version earlier than 2.2, you will probably encounter an issue during our automated database migration. To avoid that issue, you will need to clean up your statistics by executing some SQL commands described in issue [[XWIKI-8129>>http://jira.xwiki.org/browse/XWIKI-8129]]. Be sure to apply these before attempting the migration. If your are in doubt, apply it, these could not hurt. If you don't, you will face duplicate IDs errors during the migration process, and it will fail, preventing you to run your wiki.
