Upgrade 5.2.x to 5.4

Hello Edin,

did you read the Section "Upgrading to DD OS Version 5.4.0.8" in the Release Notes ?

I did it this Way on 2 DD510 Systems and it worked fine

Regards Werner

I could upgrade within the same version 5.2.x to another 5.2.x, but not straight to 5.4. Furthermore, the 5.3 is deprecated and there is no download available to create a single-hop upgrade from 5.2 > 5.3, and then to 5.4. Anyone have any ideas?

Others already tackled path part - let me enlighten you in respect to 5.3.  5.3 and 5.4 are the "same".  What happened here was that at the time of EMC World 2013, engineering released 5.3 code (DA).  However, by that time, new DD hardware models were not in - that happened couple of months after.  5.3 didn't support those, but 5.4 did.  And since 5.4 was 5.3 it was logical to kill 5.3 which is nothing more than 5.4 minus support of new models.  Obviously, some roadmaps were either executed a bit later or a bit faster, but these are harmonized now by killing 5.3 for good.  That means that some 5.3 should be considered as skipped version as it never existed.  For example, 2 hop upgrade path support (eg. 4.9->5.1, 5.0->5.2) in this case means that 5.1->5.4 is valid and supported.

Hi Edin,

Were you able to perform the upgrade of your system to 5.4?  Please let us know if you need any assistance.

Hi everyone,

first of all, thanks, @Hrvoje, I knew the HW upgrade path and was aware of the DDOS5.3 hop to 5.4. Therefore, I never attempted to upgrade to 5.3, but since I could not do the upgrade from OS 5.2.3.1-387929 to 5.4.0.8-404909, I just wanted to see if it is possible to do it first to 5.3 (having in mind the upgrade path you had to follow in the past).

I have skimmed through the release notes and will test the procedure (I also have access to DDPG) and let you know the results soon.

Thank you all for participating in the discussion.

Update @all: I did an upgrade from 5.2.1 to 5.4.0.8-404909 and it went perfectly. I'm guessing that the package I had back then, when I tried to do the 5.2 > 5.4 on a different box, was somehow corrupt.

You can always run precheck to make sure package is ok (though in this case, you still leave the space there might be an issue with box itself as it was different one).

I'll check the box in question once again. Had another 5.1>5.4 upgrade, it went without a single hiccup. The box was active and in full working order for 418 days before the upgrade

I have done this a number of times and am doing it again, tomorrow... You can upgrade two levels in the same main level family... Example 5.2 -> 5.4... or in this case 5.1 -> 5.4 because there is no official 5.3 release.

Even I open a place holder upgrade ticket with Data Domain support team. Go to Support.emc.com, create a case and instead of Technical Issue, choose UPGRADE. This is a schedule ticket, so do this a few days in advance.

If it is a remote ddos upgrade, ensure your IPMI (remote power similar to ILO) is configured and tested before you start.

Yes, I love my job and my bosses are wicked cool!
