how can I migrate all my data and configuration for matrix synapse and Riot.Im installed on the system to another one VM ? Can I backup and restore all the rooms (created with Riot.IM) , the chat logs and the users and migrate all the content to another machine ?
The old system is configured without using docker.
Thank you
All the applications are decentralized and there will be configurations file which are holding your server and connection information, Remaining all the data is stores in the Database which you are using. So we have client in your case Riot , Matrix Synapse and Database(Migration)
We have a configuration file named config.json (default) which has the URL's of your synapse server. While Migrating copy the values of the from your existing riot config file to your new riot config file.
Similar to the Riot there is a homeserver.yaml and conf.d/server_name.yaml files in matrix-synapse installation folder, which has all the configurations. Copy the contents from these files to new matrix files and you are done with client and interface, Let's get into Data Migration.
SQLITE3 to PostgreSQL follow the command
create dump file from sqlite
sqlite database .dump > /the/path/to/sqlite-dumpfile.sql
copy that sql dump file to PostgreSQL
/path/to/psql -d database -U username -W < /the/path/to/sqlite-dumpfile.sql
Old PostgreSQL to new PostgreSQL
Create a dump file as backup from older PostgreSQL
pg_dump dbname > outfile
Restore the data from this dump
psql dbname < infile
Using Database migration GUI tools such as Pentaho or dbsoft . Follow the dbsofts article
You can refer to element docs on migration, matrix docs and SQLite to PostgreSQL
