@umami/migrate-v1-v2 v0.15.0

@umami/migrate-v1-v2

Script for migrating data from Umami v1 to v2.

Requirements

• Database schema must be in sync with the latest v1 Umami repo. The script will query the prisma migrations table to ensure the latest migrations have been ran.

Important

• Backup your target database prior to use. Potential data loss may occur if the migration is interrupted.
• For users with larger datasets (5M+), the migration may take while. Please plan accordingly.
• The script will NOT migrate any event data into v2.
• The script will ask you if you want to drop your v1 tables after the migration is complete.
• If an event_data table is found populated with data, it will be renamed to v1_event_data but not dropped.

Running migration

There are two ways to run the migration script.

1. Running inside the Umami folder

cd umami
yarn add @umami/migrate-v1-v2
npx @umami/migrate-v1-v2

2. Running standalone

Install

git clone https://github.com/umami-software/migrate-v1-v2.git
cd migrate-v1-v2
yarn install
yarn build

Configure

Create an .env file with the following variable defined:

DATABASE_URL={connection url}

Run

yarn start

Troubleshooting

• If your DATABASE_URL is localhost and the migration can't connect to the database, try changing to an IP address, for example: 127.0.0.1.
