I have the database files, /data/db/ (these are from the version 3.6.3 MongoDB)
But I looked the documentation of MongoDB up and I saw and it isn't possible anymore to install the MongoDB 3.6.3.
So how am I able to update the old database files to use them with the version MongoDB 4.4
Thank you very much for your help!
You must do it one by one:

I’m running MongoDB shell version: 2.0.7 and I would like to make a backup of my database and upgrade my server to the latest version. so, I was wondering:
Is it possible to make a backup of the database since “mongodump”
doesn’t work. What options do I have?
Is it possible to import that
backup into a new server running MongoDB shell version v5.x ?
Thanks
I want to update my wamp server from 2.5 to 3.0.6 because I need PHP 5.6 or above for a project. But there are a lot of databases and projects on wamp 2.5, so I want to update it instead of uninstalling older version and install wamp 3.0
What is the simple and best way to achieve it??
You can upgrade WAMPServer 2.5 directly to WAMPServer 3.0.3 and from there to the latest version which is V3.0.9 (at the time or writing this answer). This version has PHP7.0 already installed in it, and many ADDON versions of PHP available if the version that comes with WAMPServer install is not the one you want including PHP7.1.
See the backup repo for WAMPServer
Download WAMPServer 3.0.3 which allows a direct upgrade from WAMPServer 2.5
Then upgrade WAMPServer to V3.0.9.
Then ADDON whichever version of PHP / Apache / MySQL / MariaDB that you want to use.
Then backup your databases, using your existing version of MYSQL.
Then switch to which ever version of MySQL you now want to use, and restore all your databases.
It is possible to update mongodb (Currently in version 2.0.6 and I need > 2.2) and keep databases ?
Mongodb running on Debian 7
MongoDB 2.0 data files are compatible with 2.2-series binaries without
any special migration process. However, always perform the upgrade
process for replica sets and sharded clusters using the procedures
that follow.
As said on the mongodb release notes. Also when your making an upgrade, since your current version is 2.0.6 you need to upgrade to 2.2 first.
If you want to go up to the latest version you have to keep upgrading version one by one as said on the release notes here.
Upgrading a Standalone version
Download binaries of the latest release in the 2.2 series from the MongoDB Download Page.
Shutdown your mongod instance. Replace the existing binary with the 2.2 mongod binary and restart MongoDB.
I have a mongodb standalone instance in my ubuntu. According to official docs I replace mongod binary then I restarted mongodb using sudo service mongodb restart command, and restarted mongod binary also. Then when I check version using mongo --version. It's still 2.4.10. But when I check mongod version it's 2.6.1. Is it okay? I installed mongodb in my local machine using this guide. If it correct then I will upgrade my production server.
It sounds like you have upgraded your mongod server to 2.6.1 but still have an older version of the mongo shell in your path.
Technically that isn't a major issue for most usage as the older 2.4 shell can still connect and run common commands.
However, there are 2.6-specific shell helpers & features you'll be missing out on such as Bulk() operations and user management commands with user-defined roles.
If you have an open mongo shell, you can check the versions of both the mongo client and the mongod server you are connected to.
Ideally the major versions should match, eg:
> version() // Version of the `mongo` shell
2.6.1
> db.version() // Version of the `mongod` server this shell has connected to
2.6.1
The upgrade guide you have followed is assuming you are not using the packaged versions of MongoDB -- the guidance here could definitely be improved.
A better (and typical) approach for Ubuntu is to install MongoDB using the standard packages: Install MongoDB on Ubuntu. This would allow you to get software updates via the normal apt-get update process.
Yes. It's okay. The 2.6.1 version is a small update with bugfixes after version 2.6. But it's still the same major version.
