# Grafana SQLite to Postgres Database Migrator
[![Go Report Card](https://goreportcard.com/badge/github.com/percona/grafana-db-migrator)](https://goreportcard.com/report/github.com/percona/grafana-db-migrator)

## Background

This project was forked from [wbh1/grafana-sqlite-to-postgres](https://github.com/wbh1/grafana-sqlite-to-postgres)

## Prerequisites
You **must** already have an existing database in Postgres for Grafana.

Run `CREATE DATABASE grafana` in `psql` to make the database. Then, start up an instance of Grafana pointed to the new database. Grafana will automagically create all the tables that it will need. You can shut Grafana down once those tables are made. We **need** those tables to exist for the migration to work.

## Compatability
Tested on:

| OS             | SQLite Version | Postgres Version | Grafana Version |
| -------------- | -------------- | ---------------- | --------------- |
| MacOS          | 3.24.0         | 11.3             | 6.1.0+          |
| CentOS 7/RHEL7 | 3.7.17         | 11.3             | 6.1.0+          |
| Fedora 36      | 3.36.0         | 15.0             | 9.2.0           |

## Usage
```
usage: Grafana SQLite to Postgres Migrator [<flags>] <sqlite-file> <postgres-connection-string>

A command-line application to migrate Grafana data from SQLite to Postgres.

Flags:
  --help       Show context-sensitive help (also try --help-long and --help-man).
  --dump=/tmp  Directory path where the sqlite dump should be stored.

Args:
  <sqlite-file>                 Path to SQLite file being imported.
  <postgres-connection-string>  URL-format database connection string to use in the URL format (postgres://USERNAME:PASSWORD@HOST/DATABASE).
```
### Use as Docker image
1. Build docker image: `docker build -t grafana-sqlite-to-postgres .`
2. Run migration: `docker run --rm -ti -v <PATH_TO_DB_FILE>:/grafana.db grafana-sqlite-to-postgres /grafana.db "postgres://<USERNAME>:<PASSWORD>@<HOST>:5432/<DATABASE_NAME>?sslmode=disable"`

## Example Command
This is the command I used to transfer my Grafana database:
```
./grafana-migrate grafana.db "postgres://postgres:PASSWORDHERE@localhost:5432/grafana?sslmode=disable"
```
Notice the `?sslmode=disable` parameter. The [pq](https://github.com/lib/pq) driver has sslmode turned on by default, so you may need to add a parameter to adjust it. You can see all the support connection string parameters [here](https://godoc.org/github.com/lib/pq#hdr-Connection_String_Parameters).

## How it works
1. Dumps SQLite database to /tmp
2. Sanitize the dump so it can be imported to Postgres
3. Import the dump to the Grafana database
