 ===== Migration script - "spacksearch" =====
+==== Method 1 ====
 If you need to find a list of packages or modules which correspond to the software you have been using until now, you can use the alias **spacksearch** to do that

 ==> Get some additional info with 'spack find -lvd mypackage', e.g.:

+==== Method 2 ====
+Add this function to your ''.bashrc'' file:
+<code>
+## spack command wrapper, so we can include our own `spack something`
+## commands, like `spack search`:
+spack () {
+    case "$1" in
+        "search")
+            python3 /opt/sw/spack-scripts/search/search.py "$2"
+            ;;
+        *)
+            command spack "$@"
+    esac
+}
+</code>
+Usage example:
+<code>
+skylake [user@l41 ~]$ spack search asd
+==> The package hash asd refers to python and belongs to vsc4 as:
+     python +bz2+ctypes+dbm~debug+libxml2+lzma~nis~optimizations+pic+pyexpat+pythoncmd+readline+shared+sqlite3+ssl~tix~tkinter~ucs4+uuid+zlib
+==> Searching similar python modules at skylake...

+===== Continue with old spack environments =====
+You may also continue to work with the spack environments. If you wish to do so you need the following commands:
+== On zen3 ==
+<code>
+source /opt/sw/spack-0.17.1/share/spack/setup-env.sh
+spacktivate zen3
+</code>
+== On skylake ==
+<code>
+source /opt/sw/spack-0.19.0/share/spack/setup-env.sh
+spacktivate skylake
+</code>
 <box 80% round red|Warning>This approach is not recommended and we will no longer maintain the spack environments or install new packages there</box>
