The table already shows that as an unvalid upgrade path. Not sure why you tried even when the documentation doesn't show that as an upgrade path.

There won't be any upgrade path of 7.1(5) to 8.0(x).

The next upgrade path will be until 8.5(1) is released.

For the time being, you reached a dead end.

7.1(5) does not support direct upgrade to version 8.0.  This is one of the trade-off's and among reasons I choose to stick with 7.1(3).  Your options for upgrade from 7.1(5) are to wait until 8.5(x) or basically the official first non dot zero release is.

I'll put this as simply as possible:


You CANNOT upgrade from 7.1(5) to 8.0.  You will have to wait for 8.5(1) to be released.


The only other option and you will need to read the release notes for 7.1(5) to see if this is supported:


You would have to revert back to an earlier version (i.e., switch partitions) from 7.1(5) to the previous version (installed on the inactive partition).


Depending on that version, you would need to go to 7.1(3) and then you can upgrade to 8.0.


When you upgraded to 7.1(5), you basically set yourself up to be in the situation where you cannot upgrade to any version of 8x BEFORE 8.5(1) is released.

You cannot use a downloaded image to downgrade a callmanager... What David is suggesting that you COULD do are the steps below, however, there are lots of reasons NOT to do this, mainly:


- If you revert to the older version of CUCM you have on your inactive partition, you will LOSE any configuration you have done since then

- You shoudl first go to CM Platform Admin, Settings/Version and see what 'inactive' version you have. Then check that against the upgrade matrix to verify what upgrades you would need to do to get to the 8.0 version you want.

- If the system has never been upgraded (i.e. was built as 7.1.5) then you won't have an earlier version to 'switch' to.


If you really need to do this, then:


1) Go into CM Platform admin, go to Settings/Version and press 'Switch Versions'.

2) You will then lose any admin changes made since you upgraded to the current version, and will go back to the old version of CCM. You would need to do this on each server.

3) From there, you could upgrade using the path you identified from the upgrade matrix.


My advice would be to not do any of this; I get the impression you don't have much CallManager experience and you are therefore probably not in a position to either fix it when this goes wrong, or know what the implications of rolling back to an older configuration would be.


You should probably wait until a newer 8 release arrives as pointed out by Java earlier.


What are you trying to fix by upgrading?

Hi


OK, so we're getting somewhere now. I'll try to summarise what you've been told several times above.


Youu CANNOT UPGRADE 7.1.5 TO 8.0.


You CANNOT DOWNGRADE using downloaded media.


You CAN wait until a new release of 8.x that supports upgrade from 7.1.5.


You CAN install 8.0 as a new install, lose all configuration, and completely reconfigured your system from the ground up.


Regards


Aaron

Ditto to Aaron's points. You can't downgrade by running an ISO image that you downloaded. And, while I said you might be able to revert to the inactive partition and work your way up from there - there are plenty of reasons not to do that.


If I were you, I'd wait to for 8.5(1).

Thanks dear


I understood everything but I thought maybe there should be some ways cisco introduced.


Otherwise it's ok I got it already


I was just trying to find the way.


Thanks for your information. Now I will try to do fresh installation.




Best regards,

Seems like they are some knowledgeable folks on this thread.  Thanks for the compatibility matrix link.  Here are my questions....


We are running


7.1.3.33019-1



First question:


I don't see our exact version listed anywhere on the compatibility matrix.  Do references to 7.1(3) include/encompass our version?



Second question:


I really need to know as soon as 8.5 is released, there is a big organizational push here.  Which software notification do I set myself up to receive on the Cisco support site to get this notification?




Thanks in advance!

Hi Kristy,


Your current CUCM version can be upgraded to any current 8.x version



For Notifications (set up Communications Manager > Software Updates > Any Version)

Kristy,


If I can piggy tail off of Rob (aka The Man), allow me to say this:


Stay on 7.x as long as you can and just wait for 8.5.  If you go to an 8.0 release, I'm pretty sure you'll regret it.  I do not have an official date but 8.5(1) should be released Q4 2010 (so by year's end).  However, that's always subject to change.

I need to upgrade it to version 8.


You have been told that is not possible to upgrade three times already.


Subscribe the Software Update contract, obtain 8.0 media, do a fresh install then restore a config from backup.
