Commitcrm V8 to V15

We setup a new V15 server to test can we just import V8 data into V15 if possible is there a doc explaining the steps thank you.

The Upgrade Program is the only way to fully convert your data from version 8 to version 15 of RangerMSP. Running it will move your system directly to version 15 while preserving all your data, settings and customizations. You can always export the accounts list, etc. and import it to your trial install, however this will probably won't be the same. In case you are interested in learning what's new in each of the versions beyond version 8, please use the following links to learn more about each version:

What's new in version 9, 10, 11, 12, 14, 15.

Hope this helps.
