Hi. I installed MySQL 5.7 on Ubuntu 16.04 via apt and created a Database for our Developers. Now i added 2 Slaves to that Master DB Server in the hope that i can migrate these 3 Servers to a Percona Cluster. What i did is: Installing 3 Servers Ubuntu 126.04 and MySQL 5.7 Server via apt from the Ubuntu Sources. Created one Master and 2 Slaves Replication (wich is working fine) On 3rd. Server uninstalled mysql 5.7 server and backed up /var/lib/mysql folder as well as /etc/mysql/mysql.conf.d/mysqld.cnf added percona Sources to apt like in this How-To: [url][https://www.percona.com/doc/percona-repo-config/apt-repo.html[/url]](https://www.percona.com/doc/percona-repo-config/apt-repo.html%5B/url%5D) try to install percona xtradb cluster server via apt. But that ended in an error and xtradb server could not be installed. Is there a How-To or some more information on how to move from standard MySQL 5.7 Server (with slaves) to a Percona Cluster? regards Dirk ---

I presume you got it pxc cluster working as per this thread.

I have a clean installation of Percona Cluster running, but my new task is now to migrate from MySQL Master with 2 Slaves to Percona Xtra DB Cluster. ---

There are multiple options. You probably get in touch with Percona consulting they can help you migrate in safer and quicker way. Here is a process that generally is a way to go: - You can configure PXC cluster to act as async slave and let it replicate from the master (through async replication). - Once PXC server has caught up with MASTER and then replication lag is down to 0, you can then simply switch over your application to use PXC cluster and turn-off existing MASTER and slave. ---

So there is no way to turn a MySQL 5.7 from Ubuntu Repositories into i Cluster? Do i understand you correct: - create a new Cluster with 3 Nodes - add one Node as Slave to the Master - when Slave caugth up with master change Application access from Master to Cluster That sounds like a simple thing to do. One possible Scenario for me would also be to just “copy” the Data from Singel MySQL Server to the Cluster, but i had my problems coping the data from the master to a Percona Cluster Server. What would be the best way to… lets say “dump” the data from the Master to a working PXC? (mysqldump didnt do what i wanted it to do, iirc) ---

No Suggestions on my Question on how to just copy the data?
