  • Just let it overwrite. You shouldn't be changing system templates anyway. If you have good reason then update your question. Feb 19, 2019 at 10:12

1 Answer 1


You should let the item be overwritten by the upgrade as

  1. The item is for the Sitecore Path Analyzer to work.

    Normally, you should not be updating the default items of Sitecore with custom data since those are system based items.

  2. You are moving from 8 to 9, so there have been lots of changes in terms of the Sitecore Analytics.
