Migrations.migrateTo() fails if not in server/main.js

[hanskohls]

I have written the following migration that works fine if run from the server/main.js file ...

import '../imports/startup/server';

import { Meteor } from 'meteor/meteor';
import { Migrations } from 'meteor/percolate:migrations';
import { Tags } from '../imports/api/collections/tags/tags.js';


Migrations.add({
  'version': 1,
  'name': "Add multi practice capability to user.",
  'up': function(){
    // the users are assumed to be the owner.
    
    const ownerTagId = Tags.findOne({name: "Practice Owner"})._id;
    if(!ownerTagId){
      return;
    }
    const search = { $and: [
      {practiceId: { $exists: true }},
      {practices: { $exists: false }}
    ]};

    let users = Meteor.users.find(search);
    users.forEach(user =>{
      const practice = {
        id: user.practiceId,
        tags: [ ownerTagId ],
        active: true
      };
      const practices = [practice];
      Meteor.users.update(user._id, {$set: {practices: practices}});
    });
  },
  'down': function(){
    const users =  Meteor.users.find();
    users.forEach((user)=>{
      Meteor.users.update(user._id, {
        $unset: { practices: "" } 
      });
    });
  }
});

Meteor.startup(()=>{
  Migrations.migrateTo(1);  
});

However I really wanted to have a separate migrations.js file or maybe even one per version to sit in the /imports/startup/server folder.

However when trying to run that way - despite having all imports working, I get an error like this:

W20161111-23:36:20.538(0)? (STDERR) TypeError: Cannot read property 'findOne' of undefined

It appears that Migrations._collecction is not defined in the getControl method.
