Migrating Confluence 4.3 linux to windows - not all plugins transferred

[Jacob Boyko]

I'm in the process of migrating our production Confluence 4.3.0 to a new windows server:

I've got the new system up and running, but not all of the user installed plugins have migrated.

* System Info:

** Server live:

*** Ubuntu Linux 2.6.31-14-server; MySQL 5.1.37-1ubuntu5.

** Server test:

*** Windows Server 2008 R2 64 bit; MySQL 5.5.28.

* The version of Confluence is the same in both instances.

* I've used an XML backup performed when no other users are online.

* I've synced the home directories, excluding some variations in the {{confluence.cfg.xml}} (license, connection URL to isolate from live system)

Interestingly, many of the User-installed Plugins appear in the test server under System Plugins, and the Configuration sidebar has different options for plugins.

As we saw through the ticket raised by you on Atlassian Support, it was caused by data migration failure was caused by an oversight in the MySQL max allowed packet size configuration.

The steps reproduced:

1. Choosing InnoDB ONLY during install, and:

2.

[mysqld]
collation-server=utf8_bin
max_allowed_packet=32M
