Magento migration 1.9.2.3 to 2.0.2 issue

Question

I am trying to migrate magento 1.9.2.3 to 2.0.2. I have installed both magento 1.9.2.3 and 2.0.2.

Migration tool was not installed so i downloaded files from git and used in my path E:\wamp\www\migr20\vendor\magento.

Now i trying to execute this code:

php migr20\bin\magento migrate:data -r E:\wamp\www\migr20\vendor\magento\data-migration-tool\etc\config.xml

And I get this error:

[InvalidArgumentException] Command "migrate" is not defined.

What was the mistake here? How to solve this?

Answer 1

Some of the files used for migration are missed when manually used the migration tool. I have solved by reinstalling magento2 and installing magento-migration-tool using composer config repositories.magento composer https://repo.magento.com in command prompt.

Answer 2

I'd imagine it's most likely some autoload files missing if you manually added the files. Try installing the migration tool using composer.

Answer 3

Whenever Magento2 says it is not recognizing the argument of the command line tool, try to do a DI compile.

rm -rf var/{di,generation}
bin/magento setup:di:compile

It might happen that you have added a module, in this case the migration tool, and you need to (re)compile the code first in order for it to be available.
