After upgrading from v4.5.2 to v4.6.x, we have lost all Dashboards and Data Sources

We have Grafana installed on Windows 2008 R2, to upgrade we completed the following

i. stop the Grafana service
ii. switch over from from 4.5.2 to 4.6.x
iii. copy over the custom.ini from the old 4.5.2 to 4.6.x
iv. start the Grafana service

When logging into Grafana the Dashboards and Data Source are gone.

We have completed this upgrade process a few times before without issue until the 4.6.x version.

Any ideas where I’m going wrong ?

Thank-you for your time.

You missed the data folder, that is where the database is stored
