We have a Ubuntu Server 13 physical and we want to do a clean installation, and migrate everything to the new server 16.04 . Is there a tool that allows you to migrate everything easily? That is, they can be moved:
In case there is no tool, what procedure would be the correct one to move the folders and that the company is not affected by this procedure?
The best way to do clean migration is to install your Operating System again. I would recommend you virtualize. The reason is for the flexibility. But that does not solve the migration issue. It uses KVM which is very good. Then create a virtual machine Ubuntu Server 16.04 LTS and install your applications one by one. Document the entire process. It will help you for future migrations. Save your configuration files. A magic tool that does this whole process does not exist. The best way is to urge it and see if everything works for you.
When finished. Use the new Server but do not erase the old, until a few weeks pass and you see that everything works fine.
First of all, thank you very much for responding, about 20 days ago we did the migration, basically what we did was make a copy preserving the permissions using "cp -r" the basic folders like: bin, etc, home, usr, var .
To migrate users we use the information of this pagina .
