I would suggest upgrading Marlogic to version 5 then 6 and then 7. I think
that’s what MarkLogic recommends in the Installation document as well. Its a
big jump directly going from Version 4 to Version 7.

Hi Gene,
The "missing journal file" warning won't stop the restore. I'd recommend filing
a support case and working things through that channel.
Wayne.

Was this done from a MarkLogic database backup (that is what my assumption
was)? Is it just that forest that is having trouble mounting? How big is this
backup (size and number of forests)? Are you restoring into the exact same
topology as you backed up from (that is what restore expects)?

Subject: Re: [MarkLogic Dev General] ML 4.2 backup restore to ML 7.x
Thank you Danny,
That is what I am trying to do.
Here is the text of an email I sent internally about it.
We have an NAS mount connected to both clusters. On the ML 4.2 side it is
read/write.
On the ML 7.x side it is mounted read only.
I have not been able to complete a restore from that location either by
database restore or forest restore.
The access to the /Marklogic_temp/ mount may need to be read write. When the
actual restore process gets to 00:00:00 estimated time left, it just sits there
with the forest state saying “recovering”
I see this message in the logs at that point:
Mar 28 16:01:02 MarkLogic: Missing journal file
/mldata02/RestoredForests/dodge-daily-forest01/Journals/Journal1-19700101000000-0-0-0
I have waited 30 minutes past the time it said it had finished copying data and
still no completion of the restore.
Any help would be appreciated as we are supposed to perform the actual process
from ML 4.2 QA to ML 7.x QA over the weekend.
Gene

I can’t say that I have done this, but I would expect it to work. I would
expect that, as soon as it mounted the db in 7, that it would start reindexing
(if reindexing is enabled).
I would test it first, but I think it will work.

Has anyone successfully backed up a database on ML 4.2-7 and restored it in a
new environment with a fresh ML 7.0-2.1 install?
