There is code in place that should prevent duplicate revisions from being uploaded, so it should be fine to rerun the step after this fix.

In vault/import/nuwiki.php, find:

Code:

$this->db->query_write("

Replace with:

Code:

$this->registry->db->query_write("

The bytes-changed metric may be incorrect for some revisions that were already imported before this fix. This should issue would no longer exist after the upgrade to VaultWiki 4 since the metric will be calculated differently.

Thanks. Is Vaultwiki 4 around the corner then?

When running it again I get this:

Code:

I guess I should start over with a new copy of my database? Or should I wait for Vaultwiki 4?

You should not need to start with a new database or wait for VaultWiki 4 if you are fine with one metric being off -- next to revisions it usually has +/- integer, to indicate the change in byte-size for the revision. For any messed up metrics, it will instead say +total_size

This should be the last error here, since this was the only new step added to the import process since your tests on other versions. Find:

Code:

" . implode("\n", $updated) . "

Add after:

Code:

END

I will keep on copying my database and performing a test migration / import until I get a flawless result and all the bugs are ironed out.

I did try the code above out on the current migration test, and it doesn't give an error anymore.
