Sebastien,
please consult http://dev.mysql.com/doc/mysql/en/Upgrading-from-4.0.html.
For InnoDB, the following is the most important upgrade note:
"
Upgrading: If you have stored characters < ASCII(32) to non-latin1 non-BINARY indexed columns in MySQL versions <= 4.1.2, then you have to rebuild those tables after you upgrade to >= 4.1.3. The reason is that the sorting order of those characters and the space character changes for some character sets in 4.1.3. See the MySQL/InnoDB-4.1.3 changelog for a precise description of the cases where you need to rebuild the table.
"
Also the behavior of LOCK TABLES with InnoDB has changed since 4.0.14. See http://dev.mysql.com/doc/mysql/en/News-4.1.7.html.
Best regards,
Heikki Tuuri

Subject: Upgrade glitches
Hi,
I am about to upgrade from mysql-standard-4.0.14 to mysql-standard-4.1.7 on two Red Hat ES 3 server (master/slave circular relationship).
I would like to know about any glitches I might face while doing so... Has anyone had any problems or bugs with any incompatible directives. Here is the config:
[client] port = 3306 socket = /tmp/mysql.sock
[mysqld] port = 3306 socket = /tmp/mysql.sock skip-locking key_buffer = 256M max_allowed_packet = 1M table_cache = 256 sort_buffer_size = 1M read_buffer_size = 1M myisam_sort_buffer_size = 64M thread_cache = 8 query_cache_size= 16M max_connections=400 thread_concurrency = 8 log-bin server-id = 2 master-host = xxx.xxx.xxx.xxx master-user = nobody master-password = 123abc999 master-port = 3306 log-bin
innodb_data_home_dir = /usr/local/mysql/data/ innodb_data_file_path = ibdata1:10M:autoextend innodb_log_group_home_dir = /usr/local/mysql/data/ innodb_log_arch_dir = /usr/local/mysql/data/ innodb_buffer_pool_size = 256M innodb_additional_mem_pool_size = 20M innodb_log_file_size = 64M innodb_log_buffer_size = 8M innodb_flush_log_at_trx_commit = 1 innodb_lock_wait_timeout = 50
[mysqldump] quick max_allowed_packet = 16M
[mysql] no-auto-rehash
[isamchk] key_buffer = 128M sort_buffer_size = 128M read_buffer = 2M write_buffer = 2M
[myisamchk] key_buffer = 128M sort_buffer_size = 128M read_buffer = 2M write_buffer = 2M
