I want to move my discourse instance to a new server, however when I download a backup form current server and try to upload to new server, I get the following:

> There has been an error while uploading ‘cs-uni-2016-09-16-155132-v20160905092148.tar.gz’: The backup filename contains invalid characters. Valid characters are a-z 0-9 . - \_.

So I changed the backup filename to something that was accepted, is that why I am getting:

> EXCEPTION: Migration version is missing from the filename.

Why doesn’t discourse accept uploads for restore ?

I maybe wrong, but it may be related to this

> <https://github.com/discourse/discourse/blob/512922d7767c84615b8b77089e34ede244a88c7f/app/controllers/admin/backups_controller.rb#L122>

From this commit:  
[https://github.com/discourse/discourse/commit/512922d7767c84615b8b77089e34ede244a88c7f](https://github.com/discourse/discourse/commit/512922d7767c84615b8b77089e34ede244a88c7f)

And the fact that `-` may need to be escaped like `.` is. Alternatively, if you list `-` at the very end, it should work too but being between two characters, it thinks it is trying to define a range.

So either  
`/^[a-zA-Z0-9\.\-_]+$/` or `/^[a-zA-Z0-9\._-]+$/` should work

Thoughts @tgxworld?

Also, I think it would be better to make the test, use ‘test\_Site-0123456789.tar.gz’ so that it utilizes all of the characters you are permitting.

@cpradio thanks for the input.

what would I change this backup filename to in order to have it be accepted: ?

`cs-uni-2016-09-16-172539-v20160905092148.tar.gz`

You wouldn’t. Core needs to adjust its logic. Then you’d get latest and it will upload just fine.

One thing you can try, and this is purely a guess to get you around the current issue, is replace the ‘-’ (a hyphen) with ‘\_’ (an underscore).

I can’t promise that will work, but it “might”.

**Edit:**  
I’ve got a meeting to get to, and then heading home. If I have time tonight and it is still unresolved, I’ll submit the PR to fix it.

The short-term answer is to edit `app.yml` and replace

```
version: stable

```

with

```
version: f7a335a64e7146166d5fdaedcfee816997f2822d

```

That’ll put you back to 1.6.1 and you’re good to go!

You’ll need to remember to change it back to `tests-passed` after it gets bumpted to 1.6.3, however!

Oh! If you were on `tests-passed` wait for me to edit this. . .,

```
version: b3c65620f341df95c58043dd5f120f5f43e62e3e

```

should take you back to beta3.

That’s what you got when you did a `./launcher rebuild app`? (I left out that step).

Well, darn. I’m operating at the edge of my expertise, but the

```
version: f7a335a64e7146166d5fdaedcfee816997f2822d

```

worked for me when I did my rebuild on `stable`

I suppose you could try

```
version: f63a797e390ed79b643cfad42837a67068549fbf

```

which is the last checkin before the filename validation one.
