documentapi ?

v1-to-v2-migrator/src/dumpSourceData.js

module.exports = () => {
  logStep('Dumping source data', true);
  const timestampFilter = config.timestamp ? [`stored: {$gte: new Date("${config.timestamp}")}`] : [];
  const createdAtFilter = config.timestamp ? [`created_at: {$gte: new Date("${config.timestamp}")}`] : [];
  const lrsIDFilter = config.source.lrsId ? [`lrs_id: ObjectId("${config.source.lrsId}")`] : [];
  const lrsFilter = config.source.lrsId ? [`_id: ObjectId("${config.source.lrsId}")`] : [];

  const statementFilter = createQueryFilter(['active: true'].concat(lrsIDFilter, timestampFilter));
  const documentFilter = createQueryFilter(lrsIDFilter.concat(createdAtFilter)); // **** Question 1

  const clientFilter = createQueryFilter(lrsIDFilter);
  const storeFilter = createQueryFilter(lrsFilter);

  return Promise.all([
    dumpCollection('statements', statementFilter),
    dumpCollection('documentapi', documentFilter), // **** Question 2
    dumpCollection('client', clientFilter),
    dumpCollection('lrs', storeFilter),
  ]);
};

Question 1 :
documentapi table not available in LRS V1.
So, I want to know about that "documentapi" referese to which table in LRS V1.

Question 2 :
const timestampFilter = config.timestamp ? [stored: {$gte: new Date("${config.timestamp}")}] : [];
can we creates a any config JSON to take timestamp and so many fixed value which are used in source code.

Please Provide any solution to perform above error.

Re: Question 1
This has occurred because there weren't any documents stored in your V1 database. You should be able to go into your Mongo database and run db.createCollection('documentapi')

Re: Question 2
In your JSON config file you can add a timestamp property in the root config object to determine at what timestamp you'd like to migrate data from. This property is used to avoid unnecessarily re-migrating data that has already been migrated into the new V2 database.

Re: Question 3
I'm 90% certain that you can just ignore the socketOptions errors. More of a warning than an error in this case.

Re: Question 4
Since your connections appear to be timing out, I'd suggest lowering the migration batch size.

Hi ryansmith94,
Thanks so much for your valuable suggestion.

I have suggestion
Please Updated the LRS V2 script for installing mongodb. because script install mongodb 2.6 and it 2.6 is very basic for perform many task.

1. It does not provide mongo shell.
   Most Important :
   When I used migration tool to update it then mongodump and mongorestore command causes problem and again we have to upgrade mongoDB again.
   So, at the time of LRS V2 installation higher mongo version will installed with installation script of LRS V2 then it reduced so many problem to us.
   Sorry for my request but it is helps to many users.
