is there any easy way to change the database from mysql to mongoDB ?
or better any one suggest me good tutorial do it
I am kind of partial to TalendOpenStudio for those kind of migration jobs. It is an eclipse based solution to create data migration "scripts" in a visual way. I do not like visual programming, but this is a problem domain I make an exception.
Adrien Mogenet has create a MongoDBConnection plugin for mongodb.
It is probably overkill for a "simple" migration but ut is a cool tool.
Mind however, that the suggestion of Nix will probably save you time if it is a one-of migration.
