.SH "DESCRIPTION"
.PP
\fBmysql_upgrade\fR
examines all tables in all databases for incompatibilities with the current version of MySQL Server\&.
\fBmysql_upgrade\fR
also upgrades the system tables so that you can take advantage of new privileges or capabilities that might have been added\&.
.PP
If
\fBmysql_upgrade\fR
finds that a table has a possible incompatibility, it performs a table check and, if problems are found, attempts a table repair\&. If the table cannot be repaired, see
Section\ \&2.11.4, \(lqRebuilding or Repairing Tables or Indexes\(rq
for manual table repair strategies\&.
.PP
You should execute
\fBmysql_upgrade\fR
each time you upgrade MySQL\&.
.PP
If you install MySQL from RPM packages on Linux, you must install the server and client RPMs\&.
\fBmysql_upgrade\fR
is included in the server RPM but requires the client RPM because the latter includes
\fBmysqlcheck\fR\&. (See
Section\ \&2.5.5, \(lqInstalling MySQL on Linux Using RPM Packages\(rq\&.)

On Windows Server 2008, Vista, and newer, you must run
\fBmysql_upgrade\fR
with administrator privileges\&. You can do this by running a Command Prompt as Administrator and running the command\&. Failure to do so may result in the upgrade failing to execute correctly\&.

You should always back up your current MySQL installation
\fIbefore\fR
performing an upgrade\&. See
Section\ \&7.2, \(lqDatabase Backup Methods\(rq\&.
.PP
Some upgrade incompatibilities may require special handling before you upgrade your MySQL installation and run
\fBmysql_upgrade\fR\&. See
Section\ \&2.11.1, \(lqUpgrading MySQL\(rq, for instructions on determining whether any such incompatibilities apply to your installation and how to handle them\&.
.sp .5v
.RE
.PP
To use
\fBmysql_upgrade\fR, make sure that the server is running\&. Then invoke it like this:
.sp
.if n \{\
.RS 4
.\}
.nf
shell> \fBmysql_upgrade [\fR\fB\fIoptions\fR\fR\fB]\fR
.fi
.if n \{\
.RE
.\}
.PP
After running
\fBmysql_upgrade\fR, stop the server and restart it so that any changes made to the system tables take effect\&.
.PP
If you have multiple MySQL server instances running, invoke
\fBmysql_upgrade\fR
with connection parameters appropriate for connecting to the desired server\&. For example, with servers running on the local host on parts 3306 through 3308, upgrade each of them by connecting to the appropriate port:
.sp
.if n \{\
.RS 4
.\}
.nf
shell> \fBmysql_upgrade \-\-protocol=tcp \-P 3306 [\fR\fB\fIother_options\fR\fR\fB]\fR
shell> \fBmysql_upgrade \-\-protocol=tcp \-P 3307 [\fR\fB\fIother_options\fR\fR\fB]\fR
shell> \fBmysql_upgrade \-\-protocol=tcp \-P 3308 [\fR\fB\fIother_options\fR\fR\fB]\fR
.fi
.if n \{\
.RE
.\}
.PP
For local host connections on Unix, the
\fB\-\-protocol=tcp\fR
option forces a connection using TCP/IP rather than the Unix socket file\&.
.PP
\fBmysql_upgrade\fR
executes the following commands to check and repair tables and to upgrade the system tables:
.sp
.if n \{\
.RS 4
.\}
.nf
mysqlcheck \-\-no\-defaults \-\-databases
 \-\-fix\-db\-names \-\-fix\-table\-names mysql
mysqlcheck \-\-no\-defaults \-\-check\-upgrade \-\-databases
 \-\-auto\-repair mysql
mysql < fix_priv_tables
mysqlcheck \-\-no\-defaults \-\-all\-databases
 \-\-skip\-database=mysql \-\-fix\-db\-names \-\-fix\-table\-names
mysqlcheck \-\-no\-defaults \-\-check\-upgrade \-\-all\-databases
 \-\-skip\-database=mysql \-\-auto\-repair
.fi
.if n \{\
.RE
.\}
.PP
Notes about the preceding commands:
.sp
.RS 4
.ie n \{\
\h'-04'\(bu\h'+03'\c
.\}
.el \{\
.sp -1
.IP \(bu 2.3
.\}
\fBmysql_upgrade\fR
also adds
\fB\-\-write\-binlog\fR
or
\fB\-\-skip\-write\-binlog\fR
to the
\fBmysqlcheck\fR
commands, depending on whether the
\fB\-\-write\-binlog\fR
option was specified on the
\fBmysql_upgrade\fR
command\&.
.RE
.sp
.RS 4
.ie n \{\
\h'-04'\(bu\h'+03'\c
.\}
.el \{\
.sp -1
.IP \(bu 2.3
.\}
Because
\fBmysql_upgrade\fR
invokes
\fBmysqlcheck\fR
with the
\fB\-\-all\-databases\fR
option, it processes all tables in all databases, which might take a long time to complete\&. Each table is locked and therefore unavailable to other sessions while it is being processed\&. Check and repair operations can be time\-consuming, particularly for large tables\&.

.sp
.RS 4
.ie n \{\
\h'-04'\(bu\h'+03'\c

.el \{\
.sp -1

For details about what checks the
\fB\-\-check\-upgrade\fR
option entails, see the description of the
FOR UPGRADE
option of the
CHECK TABLE
statement (see
Section\ \&13.7.2.2, \(lqCHECK TABLE Syntax\(rq)\&.

\fIfix_priv_tables\fR
represents a script generated internally by
\fBmysql_upgrade\fR
that contains SQL statements to upgrade the tables in the
mysql
database\&.
.RE
.PP
All checked and repaired tables are marked with the current MySQL version number\&. This ensures that next time you run
\fBmysql_upgrade\fR
with the same version of the server, it can tell whether there is any need to check or repair the table again\&.
.\" mysql_upgrade_info file: mysql_upgrade
.\" mysql_upgrade: mysql_upgrade_info file
.\" data directory: mysql_upgrade_info file
.PP
\fBmysql_upgrade\fR
also saves the MySQL version number in a file named
mysql_upgrade_info
in the data directory\&. This is used to quickly check whether all tables have been checked for this release so that table\-checking can be skipped\&. To ignore this file and perform the check regardless, use the
\fB\-\-force\fR
option\&.
.PP
\fBmysql_upgrade\fR
does not upgrade the contents of the help tables\&. For upgrade instructions, see
Section\ \&5.1.10, \(lqServer-Side Help\(rq\&.
.PP
By default,
\fBmysql_upgrade\fR
runs as the MySQL
root
user\&. If the
root
password is expired when you run
\fBmysql_upgrade\fR, you will see a message that your password is expired and that
\fBmysql_upgrade\fR
failed as a result\&. To correct this, reset the
root
password to unexpire it and run
\fBmysql_upgrade\fR
again:
.sp
.if n \{\
.RS 4
.\}
.nf
shell> \fBmysql \-u root \-p\fR

Check the version of the server to which
\fBmysql_upgrade\fR
is connecting to verify that it is the same as the version for which
\fBmysql_upgrade\fR
was built\&. If not,
\fBmysql_upgrade\fR
exits\&. This option is enabled by default; to disable the check, use
\fB\-\-skip\-version\-check\fR\&. This option was added in MySQL 5\&.6\&.12\&.

\fB\-\-write\-binlog\fR
.sp
Cause binary logging to be enabled while
\fBmysql_upgrade\fR
runs\&. In MySQL 5\&.6\&.6 and earlier, this was the default behavior\&. (To disable binary logging during the upgrade, it was necessary to use the inverse of this option, by starting the program with
\fB\-\-skip\-write\-binlog\fR\&.) Beginning with MySQL 5\&.6\&.7, binary logging by
\fBmysql_upgrade\fR
is disabled by default (Bug #14221043)\&. Invoke the program explicitly with
\fB\-\-write\-binlog\fR
if you want its actions to be written to the binary log\&. (Also beginning with MySQL 5\&.6\&.7, the
\fB\-\-skip\-write\-binlog\fR
option effectively does nothing\&.)
.sp
Running
\fBmysql_upgrade\fR
is not recommended with a MySQL Server that is running with global transaction identifiers enabled (Bug #13833710)\&. This is because enabling GTIDs means that any updates which
\fBmysql_upgrade\fR
might need to perform on system tables using a nontransactional storage engine such as
MyISAM
to fail\&. See
Section\ \&17.1.3.4, \(lqRestrictions on Replication with GTIDs\(rq, for more information\&.
