Migration Steps



  • Node.js has been updated to version 12.16.0 from 12.14.0, which includes security updates and small changes:
    • 12.16.0
      • Updated V8 to release v7.8 which includes improvements in performance, for example, object destructuring now is as fast as the equivalent variable assignment.
    • 12.15.0

Hi all,

I was reading the file suggested by @vooteles and found this header for the next meteor version 1.10:

v1.10, TBD

Now, what does TBD mean in this context? How should this abbreviation be interpreted here?

I looked for some understanding in google and found this meaning: task-based development, but how can this be applied in this context? …

It means To Be Disclosed (most probably).

To be determined. It’s for the release date.

It’s to be determined because it isn’t released yet.


Meteor 1.9.2 has been released just few hours ago as well. Just a patch update for Node.js.


I’m using meteor up to deploy on server, wich are the correct version to set in mup file ? With version 1.8.3 is 3.4.1.

Which version do you mean?
For the Docker image, you want something with Node 12 like abernix/meteord:node-12-base
For MongoDB, you want v4.0.6

Ok, thank you.
I looked for the mongodb version for Meteor 1.9.2 but didn’t find it, where can you see it ?
I found also a problem like my…

For now I remain on version 3.4.1 hoping that it will not give problems with meteor 1.9.2.

I had a quick look at issues on the mup repo and there are several people who seem to be using Mongo 4 without issue?

For me, mup with mongo 4.0.6 works fine.

I’m using mup with configuration:

docker: {
    image: 'abernix/meteord:node-12-base',

mongo: {
    version: '4.0.6',
    servers: {
        one: {}

But don’t works.
When I run “mup setup” this is a log:

Started TaskList: Start Mongo
[x.x.x.x] - Start Mongo

"mup logs" show this:

Instead with mongo 3.4.1 or 3.6.x works properly.

ok, thats clear now.
It’s not possible to upgrade MongoDB without upgrade it’s database, so I have installing a new server and then dump and restore data.
Now is all good ! Thanx to everyone.
