我的老板给我一项任务，即迁移安装了CRM的OpenERP V6数据库并使用CRM数据将其迁移到V8，而不会丢失任何数据
我需要知道如何实现类似的内容或如何移动数据并将数据库从v6更新到v8
更新1：
我试图使用openupgrade，我已经下载了migrate.py和run命令
python migrate.py --config=[openerp-server.conf] --database=[kamel] --run-migrations=7.0但是我alawys出错了
No user found in configuration
这是我的openerp-server.conf：
[options]
; This is the password that allows database operations:
admin_passwd = admin
db_host = localhost
db_port = 5432
db_user = odoo
db_password = odoo
addons_path = /Users/mostafa/Documents/odoo-develop/odoo8/addons,/Users/mostafa/Documents/odoo-develop/net2do_work,/Users/mostafa/Documents/odoo-develop/more_net2do,/Users/mostafa/Documents/odoo-develop/freelance_work,/Users/mostafa/Documents/odoo-develop/custom_addons
pg_path= /usr/local/bin
