Dear space Technical Team,
I have to upgrade my Dsapce 1.4.2 on Windows to 1.8.2 on Ubuntu.
The steps I follow are as under
1. I install 1.8.2 on Ubuntu.
2. Take the Backup of Dsapce 1.4.2 on Windows
3. Restore it on 1.8.2 on Ubuntu.
4. Upgrade the database using
[dspace-src]/dspace/etc/postgres/database_schema_14-15.sql
[dspace-src]/dspace/etc/postgres/database_schema_15-16.sql
[dspace-src]/dspace/etc/postgres/database_schema_16-17.sql
[dspace-src]/dspace/etc/postgres/database_schema_17-18.sql
5. Copy [dspace]/assetstore/ folder and all subdirectories to Dspace 1.8.2
on Ubuntu.
Now the problem is That Dspace is Not Showing any item in it Though it
shows all the collection in it.
I have checked the bit stream file on the database. it contain all the
items uploaded on Dspace 1.4.2 on windows.
Kindly help in this regard.

Andrew,
It is possible to perform an upgrade from an old version to a new
version. We have a note about "upgrading across multiple versions" at
the top of our new Installation docs:
https://wiki.duraspace.org/display/DSDOC18/Upgrading+a+DSpace+Installation
There's a few ways to perform this upgrade. One ways is to do it step
by step as described in the above documentation (upgrading from 1.3.x ->
1.4.x -> 1.5.x -> 1.6.x -> 1.7.x -> 1.8.x).
Another way is to just upgrade your existing database structure to be
1.8.x compatible, and then perform a "fresh install" of 1.8.2.
Here's how you could just upgrade your existing database & associate it
with a fresh install of 1.8.2:
(1) First backup everything! Also, you should try this out on a test
server before you do it on production
(2) Upgrade your existing database structure & data from 1.3.1 to 1.8.x
by running *all* of these scripts in order:
[dspace-src]/dspace/etc/postgres/database_schema_13-14.sql
[dspace-src]/dspace/etc/postgres/database_schema_14-15.sql
[dspace-src]/dspace/etc/postgres/database_schema_15-16.sql
[dspace-src]/dspace/etc/postgres/database_schema_16-17.sql
[dspace-src]/dspace/etc/postgres/database_schema_17-18.sql
These scripts basically upgrade your database structure little by little
from 1.3.x compatible to 1.8.x compatible.
(3) Install a fresh copy of 1.8.2 by following its Installation
Instructions (To do this you will need to create a fresh database
temporarily.)
(4) After installing 1.8.2, swap out the fresh database for the newly
upgraded database (from step #2 above). Either you can rename the
databases, or just change the database settings in your 1.8.2 dspace.cfg
so that now points at your newly upgraded database.
(5) Copy over all your DSpace content files (the entire
[dspace]/assetstore/ folder and all subdirectories) to your new 1.8.2
DSpace. This is where all the actual files reside in DSpace.
(6) Reconfigure and re-customize the DSpace 1.8.2 instance (as necessary).
Hopefully this helps. Again, make sure to first perform a backup just in
case!
