This guide describes how you can migrate your data from another system to Fenerum. 

## Import historical MRR

This feature allows you to import and track MRR of subscriptions prior to the start date in Fenerum.
Example use case:

- subscription is started on 01-02-2023 with quantity of 1 (MRR: 123)
- subscription is updated on 01-03-2023 with quantity of 2 (MRR: 246)
- you start using Fenerum on 01-01-2024
- you create subscription in Fenerum that starts on 01-01-2024 with quantity of 2 (MRR: 246)
- you create manual activities for the above-mentioned subscription that reflects the historical MRR of the subscription

## Import manual MRR activities through import

If you have multiple subscriptions that you need to import historical MRR for, follow the steps below:

1. Go to subscription activities.
1. Filter after type "Created new subscription".
1. Export all these to Excel.
1. In the Excel file you need to remove line under "uuid" and delete all columns to the right of _mrr_.
1. You need to change date, quantity and MRR so they are corresponding to what the MRR was at that time. ID of subscription in subscription columb and terms, needs to stay the same.

_NB_ If you only need to import historical MRR for one subscription, go to details section of subscription and click "Show all" under _Key activities_. You need to filter after type "Created new subscription" and then click _Export to Excel_.

In the Excel file you need to remove line under "uuid" and delete all columns to the right of _mrr_.

If we look at the given example, you need to do the following:

1. You need to edit the date of the first line and change it to 01-02-2023
1. Change the quantity to 1
1. Change MRR to 123, in order to get MRR of 123 in February 2023.
1. To get MRR of 246 from March 2023 and going forward until start of subscription in Fenerum, you also need to create one more line with the same subscription ID and terms.
1. On that line, you need to change date to 01-03-2023, quantity to 2 and MRR to 246.

You can see an example of this, here:

Each row without a value in the UUID-column will create a manual activity.
Save the file after making all the required changes.

Then go to the [Import data](https://app.fenerum.com/importers/import-data/) section.

Select manual activity as type of import and upload the file with manual activities.
You can see the input format when you click on the _File format descriptions_ button.

If you made any mistakes or want to make some changes to already created manual activities you can export the activities
again with the _Is manual_ filter.

You can make changes to those activities as long as they precede the start date in Fenerum and are manual activities.
The UUID-column should not be empty if you want to edit an activity.
