Be sure to have your connection strings out of your supply and vacation spot databases. This instance exhibits a connection string for Galaxy internet hosting:
mongodb://admin:passwordEncodedb@user_testcluster-01.mongodb.galaxy-cloud.io:30010,user_testcluster-02.mongodb.galaxy-cloud.io:30010,user_testcluster-03.mongodb.galaxy-cloud.io:30010/admin?replicaSet=test_replicaset
We don’t need inconsistent knowledge, proper?
So, at this step, we have to cease our software in order that it doesn’t write any knowledge to our database. After a whole cease, we are able to proceed with the migration.
