HomeIf you want to install from scratch (new and fresh installation), this guide is for you. In this post, i will guide how to upgrade to 11.3 from previous versions mainly like 11.2 through zypper dup command.
Note: Before doing this upgrade, ensure that your current system is completely update with latest packages from update repo. And also backup your DATA.
This how to will cover two main steps, one to update current system and another to upgrade the system. STEP-I is not mandatory, its just to check the update repo and system, if you are sure about update repo and updates, jump directly to STEP-II.
STEP-I:
1- You can check whether update repo is enabled or not by this command:
zypper repos --uri
2- If it is enabled, you are fine to proceed and jump to step 4, if not enable it by this command:
zypper modifyrepo --enable repo-update-11.2
Where repo-update-11.2 represents the repo name.
3- If it is not present, add it this way, (but normally it will be there):
zypper addrepo --check --name 'openSUSE-11.2-Update' http://download.opensuse.org/ update/11.2/ repo-update-11.2
Replace 11.2 with your version.
4- Now lets update the system:
zypper refresh
zypper update
Until here we are done with the update process, now is time to upgrade and start the FUN. I assume you are on 11.2 and want to upgrade to 11.3.
STEP-II:
1- The 1st thing we need to do is to disable all 11.2 repos.
zypper modifyrepo --all --disable
2- Now lets add 11.3 repos.
zypper addrepo --name "openSUSE-11.3 OSS" http://download.opensuse.org/ distribution/11.3/repo/oss/ repo-11.3-oss zypper addrepo --name "openSUSE-11.3 Non-OSS" http://download.opensuse.org/ distribution/11.3/repo/non-oss/ repo-11.3-non-oss zypper addrepo --name "openSUSE-11.3 Updates" http://download.opensuse.org/ update/11.3/ repo-11.3-update
3- You can add more repos which you used for other things, but the possibility of doing that is to break the upgrade process. Lets avoid that for the moment. Later you can add when installation/upgrading is finished. Now lets refresh the repos:
zypper ref
4- Now time to do upgrade process, there are two ways to do this. One is to use dup command which will download and install the packages. Another one is to download 1st and install later. This is your choice here.
4a- To download and install at the same time:
zypper dup
4b- To download 1st and install later:
zypper dup --download "in-advance"
Just run one command from above either 4a OR 4b. And you are done. Congratulation! and have FUN!.
NOTE: Personally i will do fresh installation either from Live CD or DVD. But its your choice here, which way you feel comfortable with, go ahead with it.
Best of luck.
