# Configuration Options
Configuration options are added at launch, either through command line options or through environment variables.
This is an example using the command line options.
./meilisearch --db-path ./meilifiles --http-addr '127.0.0.1:7700'
Here is a list of all the options and how to use them.
# Updating MeiliSearch
Getting the latest version of MeiliSearch is a straightforward process: simply fetch and install the latest binary with your preferred method (see installation above).
However, please note that prior to our official release (
v1.0), all minor updates (
v0.X) are considered breaking. Therefore, MeiliSearch databases are not compatible across versions for as long as we are in beta.
If you want to transfer your database from an outdated MeiliSearch instance to the most recent version, we recommend following the below guide.
If you get the error
Cannot open database, expected MeiliSearch engine version: X.X.X, current engine version Y.Y.Y, simply delete your database folder (defaults to
data.ms), and re-index all your documents.
# Migrating a Database to a Later Version
Using dumps, you can export your MeiliSearch data—all indexes, documents, and settings contained in your database—into a transferrable state. Then, you can re-import this data after updating MeiliSearch to the latest version.
Since the content is exported in a way that guarantees mobility, it needs to be re-indexed. If your database is large, this process can take a long time. Nonetheless, this process guarantees to migrate all settings and documents between two different versions of MeiliSearch.
If you want a complete guide on how to update MeiliSearch on DigitalOcean, please look at this GitHub issue (opens new window).
