• Install MySQL to C:\TEMP.
• Make old installation folder to mysql_old.
• copy the following folders "bin, include, lib, share, support-files" to xamp\mysql\ folder. I didn't copied the data folder
• Copied the my.ini file from old installation to new installation in xamp\mysql\bin\ folder
• Copied the old data folder to new mysql folder

• 将 MySQL 安装到 C:\TEMP。
• 将旧的安装文件夹设为 mysql_old。
• 将以下文件夹“bin、include、lib、share、support-files”复制到 xamp\mysql\ 文件夹。我没有复制数据文件夹
• 将 my.ini 文件从旧安装复制到 xamp\mysql\bin\ 文件夹中的新安装
• 将旧数据文件夹复制到新的mysql文件夹

Now after doing this I tried to start mysql from the control panel and following error displays:

# mysql-data-dir/my.cnf to set server-specific options (in this
# installation this directory is F:/xamp/mysql/data) or
# ~/.my.cnf to set user-specific options.
#
# In this file, you can use all long options that a program supports.
# If you want to know which options a program supports, run the program
# with the "--help" option.

# To configure this host as a replication slave, you can choose between
# two methods :
#
# 1) Use the CHANGE MASTER TO command (fully described in our manual) -
#    the syntax is:
#
#    CHANGE MASTER TO MASTER_HOST=<host>, MASTER_PORT=<port>,
#    MASTER_USER=<user>, MASTER_PASSWORD=<password> ;
#
#    where you replace <host>, <user>, <password> by quoted strings and
#    <port> by the master's port number (3306 by default).
#
#    Example:
#
#    CHANGE MASTER TO MASTER_HOST='125.564.12.1', MASTER_PORT=3306,
#    MASTER_USER='joe', MASTER_PASSWORD='secret';
#
# OR
#
# 2) Set the variables below. However, in case you choose this method, then
#    start replication for the first time (even unsuccessfully, for example
#    if you mistyped the password in master-password and the slave fails to
#    connect), the slave will create a master.info file, and any later
#    change in this file to the variables' values below will be ignored and
#    overridden by the content of the master.info file, unless you shutdown
#    the slave server, delete master.info and restart the slaver server.
#    For that reason, you may want to leave the lines below untouched
#    (commented) and instead use CHANGE MASTER TO (see above)
#
# required unique id between 2 and 2^32 - 1
# (and different from the master)
# defaults to 2 if master-host is set
# but will not function as a slave if omitted
#server-id       = 2
#
# The replication master for this slave - required
#master-host     =   <hostname>
#
# The username the slave will use for authentication when connecting
# to the master - required
#master-user     =   <username>
#
# The password the slave will authenticate with when connecting to
# the master - required
#master-password =   <password>
#
# The port the master is listening on.
# optional - defaults to 3306
#master-port     =  <port>

Simply remove this line from my.ini:

只需从my.ini以下位置删除此行：

    innodb_additional_mem_pool_size = 2M

It was "deprecated in MySQL 5.6.3, are removed in MySQL 5.7.4."

它“在 MySQL 5.6.3 中被弃用，在 MySQL 5.7.4 中被删除”。

(If my notes are correct, it has been "unused" since 4.1.0!)

（如果我的笔记是正确的，它自 4.1.0 以来一直“未使用”！）

To Upgrade MySql included in XAMPP (I did it on a Windows system):

1. Rename your Mysql directory to some other name.
2. Download the .msi file from the MariaDB link https://downloads.mariadb.org/.
3. Run .msi. Change the install directory to your Mysql location under XAMPP.
4. After completion, copy the old my.ini from the original mysql/bin directory to your new mysql/bin directory.
5. You should be able to start Mysql from the XAMPP control panel.

升级 XAMPP 中包含的 MySql（我在 Windows 系统上完成）：

1. 将您的 Mysql 目录重命名为其他名称。
2. 从 MariaDB 链接https://downloads.mariadb.org/下载 .msi 文件。
3. 运行.msi。将安装目录更改为 XAMPP 下的 Mysql 位置。
4. 完成后，将旧的 my.ini 从原来的 mysql/bin 目录复制到新的 mysql/bin 目录中。
5. 您应该能够从 XAMPP 控制面板启动 Mysql。
