只升级mongodb的版本极为简单，更新/替换 bin/目录下的可执行文件即可。
debian和osx上的升级，按步骤来，没什么好说的。
http://docs.mongodb.org/manual/tutorial/install-mongodb-on-debian/
切换引擎就麻烦了，新引擎的性能很诱人。
对迁移引擎来说，最大的问题是文件格式不兼容
也就是说，得把旧数据全部重新导一遍。
实现方式是设旧引擎数据库为master
设新引擎数据库为slaver
执行数据同步
旧引擎库

# Short-Description: An object/document-oriented database
# Description: MongoDB is a high-performance, open source, schema-free
# document-oriented data store that's easy to deploy, manage
# and use. It's network accessible, written in C++ and offers
# the following features:
#
# * Collection oriented storage - easy storage of object-
# style data
# * Full index support, including on inner objects
# * Query profiling
# * Replication and fail-over support
# * Efficient storage of binary data including large
# objects (e.g. videos)
# * Automatic partitioning for cloud-level scalability
#
# High performance, scalability, and reasonable depth of
# functionality are the goals for the project.
