An attempt to upgrade again to MySQL 8.0 involves: If the upgrade fails due to some errors, the server reverts all changes to the data directory. This marks the completion of the INPLACE upgrade process. Version : '8.0.12' socket : '/home/npgopala/workspace1/mysql-trunk/dbg-8.0/mysql.sock' port : 3307 Source distribution

Let me run the utility against a running MySQL 5.7 server before attempting an upgrade to MySQL. The blog on Upgrade Checker describes how simple it is to run the utility and check if there are any actions that needs to be taken prior to upgrade. We wanted this process to be simple for users and hence introduced a Upgrade Checker utility that comes with the MySQL Shell 8.0. The first step in upgrading to MySQL 8.0 is checking the upgrade preparedness of the existing MySQL 5.7 server.
This blog post describes the simple steps to be followed for performing an INPLACE upgrade to MySQL 8.0. Also while loading the databases during LOGICAL upgrade, errors might be encountered due to the incompatibilities which would require modifying the exported SQL file. The INPLACE upgrade is faster than the LOGICAL upgrade since it does not require loading of the databases after installing MySQL 8.0 version. The LOGICAL upgrade involves exporting SQL from the MySQL 5.7 version using a backup or export utility such as mysqldump or mysqlpump, installing the MySQL 8.0 binaries, and then applying the SQL to the new MySQL version. The INPLACE upgrade involves shutting down the MySQL 5.7 server, replacing the old binaries with MySQL 8.0 binaries and then starting the MySQL 8.0 server on the old data directory. The server can be upgraded by performing either an INPLACE upgrade or LOGICAL upgrade. The overview about the new features and improvements made in MySQL 8.0 can be found in the following blog.
