UCM version upgrade and failover
I'm new to the company, and I currently have a Cisco MCS 7828-H3 running UCM 6.1.1 with Unity connection 2.1.1. We had a psu go faulty on the MCS which killed the phone systems for a day, and had everyone going crazy. I figure best bet is just to buy a backup MCS off of ebay, and run it in some kind of failover config. I was also looking to upgrade to some of the newer versions. Looking at the version compatibility chart, 6.1.1 isn't even shown as compatible with my server, so I'm not sure how that worked out. The newest 8.6 is indeed compatible, but I was wondering how licensing works on this device? Does smartnet cover the upgrade for going from 6.1 to 8.6? Also, I see two machines on ebay (one of which looks beefier), but the compatibility chart doesn't show them as being compatible. Will I still be able to upgrade them to the same versions? How does failover work with this system. I really don't want to have to bother with getting any new licensing for the backup server since it will just be there in the case of an emergency (1 day every couple of years).
If a model does not show up try looking here:

Solution Overviews
If it's not the same HW most likely you won't be able to install it and won't be supported if you manage to install it but the specs do not match what is on the link.
As far a failover it's either you buy another node license and create a subscriber (which will be seamless failover for users) or you backup your config daily and when your PUB crashes you take that config and load it into the other server which will be running the exact same version as the production PUB and you also need to reach licensing in order for them to rehost the licenses from one server to the other. Obviusly the 2nd option means you'll be without phone services until you restore your config on the other server and get the licenses.

Berry 9320-version upgrade and blackberry ID fault
I upgraded my blackberry curve 9320 from version 2039 to the newly updated 2494 via blackberry desktop, ever since the upgrade, I don’t get my BBM contacts and information as well as emails.
I have put in the information for the blackberry ID and this should normally restore all BBM and email details from the back up that was done before the upgrade version, this is not the case.
I have reset and wiped all data from the phone and tried to restore from the back up that was done prior to the upgrade version, still nothing.
I have now "rolled Back" on the device version and reinstalled the downgraded version being 2039, however after restoring all information via blackberry desktop, still nothing, blackberry ID was updated and my profile connected but the BBM still wants to contact as a "new User" with all contacts and user groups gone, including email accounts that I can see on the blackberry but nothing coming in.
Please assist.
Kind regardsHi and Welcome to the Community!
With a strong carrier network signal (e.g., not merely WiFi), I suggest the following steps, in order, even if they seem redundant to what you have already tried (steps 1 and 2 each should result in a message coming to your BB...please wait for that before proceeding to the next step):
1) Register HRT
KB00510 How to register a BlackBerry smartphone with the wireless network
Please wait for one "registration" message to arrive to your Messages app
2) Delete and Resend Service Books
KB05000Delete the service book for the BlackBerry Internet Service email account from the BlackBerry smartphone
If you have no CMIME entry, then skip the deletion
KB02830 Send the service books for the BlackBerry Internet Service
Please wait for "Activation" Messages, one per already configured email account, to arrive in your Messages. If you have no already configured email accounts, please wait 1 hour.
3) Reboot
With power ON, remove the back cover and pull out the battery. Wait about a minute then replace the battery and cover. Power up and wait patiently through the long reboot -- ~5 minutes.
See if things have returned to good operation. Like all computing devices, BB's suffer from memory leaks and such...with a hard reboot being the best cure.
Hopefully that will get things going again for you! If not, then you should contact your mobile service provider for formal support.
Good luck!
Occam's Razor nearly always applies when troubleshooting technology issues!

I've to upgrade s/w on both WLCs. currently all of our APs are associated with WLC1 so I'll upgrade WLC2 1st. and then WLC1. when I ugprade WLC1 then all APs will failover to WLC2. once WLC1 s/w ugprade is done then I've to failover all APs to WLC1. how do I do that?
Plus: I found that two images on cisco website. FUS.aes and .aes file. do I have to upload both files on WLC for ugprade? which one should I upload first?Plus: I found that two images on cisco website.

Please read the Release Notes first! "FUS" firmware is meant for WAPs/WLCs in Russia, comrade.

You can pre-download the new IOS into the WAP BEFORE you reboot the WLC. This way when the WLC reboot the WAPs will too. -
I have upgraded Apple Aperture from version 2 to version 3 and I'm having a problem with the "Highlights and Shadows" adjustment. According to the user's manual, I should have access to an advanced disclosure triangle which would allow me to adjust mid contrast, colour, radius, high tonal width and low tonal width.
If anyone has any suggestions as to how to access this advanced section, I'd be most grateful.Hi David-
The advanced adjustments in the Highlights & Shadows tool were combined into the "Mid Contrast" slider in Aperture 3.3 and later. If you have any images in your library that were processed in a version of Aperture before 3.3, there will be an Upgrade button in the Highlights & Shadows tool in the upper right, and the controls you asked about under the Advanced section. Clicking the Upgrade button will re-render the photo using the new version of Highlights & Shadows, and the Advanced section will be replaced with the new Mid Contrast slider. With the new version from 3.3 you probably don't need the Advanced slider, but if you want to use the older version you can download it from this page:

Someone please help me I have an iPhone 3GS version 4.2.1 8c148a and I downloaded slotmania this morning and it won't let me play it keeps asking if I want to upgrade and I can't upgrade because phone won't let me so I'm wanting to play my game I use to could play it and farmville but for some reason it won't let me play .... Can someone help me figure out something because I'm sure their is a way I can and husband won't upgrade me and I got free upgrade and can't even get because he's cheap it's sad Hugh
What iPhone do you have? You can check in settings>>general>> about.
If you have a 3G you cannot update beyond iOS 4.2.1. The 3G is over 4 years old an was discontinued over 2 1/2 years ago. You need the latest ios to run the latest versions of some apps. If you have a 3GS you can update.
If your phone is not responding, reset it by pressing and holding down both the home button ad lock/ sleep button simultaneously until the Apple logo appears. -
I have an older iPod Touch, Model MC086LL with an IOS software version of 4.2.1. Many of the applictions which I had previously purchased were recently upgraded and they no longer can be loaded on my iPod. What is the fix?
Reload older versions from iTunes on a computer, or buy a newer device.

my ipod touch 4g upgrade to version 5 and when I connect to iTunes stays in step 2 of 7 steps: backup saved ...... 1 hour goes well and you reinstall iTunes, reconnect, etc..HELPME!!!!
Try:
- Powering off and then back on your router.
- Anything else here
iTunes for Windows: iTunes cannot contact the iPhone, iPad, or iPod software update server
- Change the DNS to either Google's or Open DNS servers
Public DNS — Google Developers
OpenDNS IP Addresses
- Try on another computer/network
- Wait if it is an Apple problem -
Using Audition 2.0 on Windows XP platform. Now have Windows 8.1 on new computer and need to upgrade and load latest version of Audition. Any suggestions? Many thanks, R.
VC6. is rather old, but you can try to convert the VC6 project using the upgrade wizard of VC2012. Depending on the content of the project your code will work more or less without problems, at least it will compile without errors.
You could also go the 2nd way and create in VC2012 a project type using the wizard that is very similar to your current VC6 projcet (MDI, SDI, Dialog Based, ...). Than you replace the files generated by the wizard with the content of your project. Sometimes
this way is more successful.
But at all the automated converting success depends on the code of your VC6 project. I had both, conversions without big problems and also conversions that need a lot changes to run on a current VC version.
Best regards
Bordon

I am running OS X, version 10.6.8 with safari 5.0.5. recently i ran one of those recommended upgrades and now Safari continually quits citing .WinASOEasyTweakVKey.Gen.tmp plug-in. how in the world do i combat this issue? thank you! I have reset Safari several times.
Another new problem is Firefox telling me, when the e-mail window is open, that the window must run in 32 bit. The window is then disabled and then i have to restart Firefox.
Thank You for any help/hope you can give me with these issues. deborahYou’ve been infected with the “Flashback” malware. See this Apple support document:
About Flashback malware
Back up all data, if you haven't already done so.
From the menu bar, select
▹ Software Update
to install the latest Java update, as well as any other available updates. That should clear the infection in most cases. You must update to the latest version of OS X 10.6 or 10.7 before you can install the Java update.
The removal tool runs automatically in the background and is then deleted. Don’t look for something to click. If the malware is removed, you’ll be notified.
After you’ve secured your system — not before — change every Internet password you have, starting with banking passwords, and check all financial accounts for unauthorized transactions. -
I keep getting a message when I try to open iphoto that says that my photo library needs to be upgraded and my library will not be readable by previous versions of iphoto after the upgrade. What do I do??
Depends - you first off need to suypply us with information since we only know what you tell us
Like what version of iPhoto are you using? Have you recently installed any iPhoto (or iLife) updates or upgrades? Do you plan to use this iPhoto library with two or more different versions of iPhoto (no possible so stop now if you do)? Where is your iPhoto library?
Anything else that you can tell us that might let us give you a good answer to your question

Upgraded to Version 10 and NO Bookmarks & associated Passwords
I am using Win 7 Pro 64 Bit
Just upgraded to Version 10 and WHAM!!! NO Bookmarks and of course all stored Passwords have gone with them.
Is there a solution or a way to "Roll Back" to the previous version?
Do not recall seeing a BIG Flashing Sign saying "BEWARE"
Have never had this problem before.
Firefox advises an update is available & I let it install
What has gone wrong this time?
I am sure I am not the only one with this problemHi mohayley, Windows 10 drivers are not planned for your PIXMA MP530.

i upgraded to the new itunes version 7 and now my podcasts on my iphone4 won't work. i get an error message "temporarily unavailable". has anyone found a solution to be able to listen to podcasts? thanks
I have the same problem, but don't expect Apple to help! I rang their help line and explained the situation and that the same experience is reported all over their forum and they would not assist unless I paid for a one year help subsciption.
This company has lost the plot! They create software that universally will not work then expect customers to pay to have it fixed. Technically I should walk straight into the nearest apple shop and ask for a refund, as the device is no longer fit for purpose!
Congratulations Apple for the best ant-promotional App on the market and your astounding lack of service ethos. -

10.1.2.3 app server, xml, and Module version="101020300" and upgrade=yes
We upgraded our app server from 10.1.2.2 to 10.1.2.3. I converted some of our Oracle Forms to xml before upgrading. I noticed the following "Module version" element and value? What version of Oracle Forms is this 10.1.0.2 , 10.1.2.2, or 10.1.2.3. When I add upgrade=yes on the compile line the fmb file dates do not change and the xml version tag stays the same in unix. Whenver I do this on windows the files dates of the fmbs do change, but the version tag also stays the same. Is it possible the 10.1.2.3 compiler uses 10.1.0.2 version for fmbs and knows there is nothing to change so it leaves the fmb untouched when upgrade=yes?
<?xml version = '1.0' encoding = 'UTF-8'?>
<Module version="101020300" xmlns="http://xmlns.oracle.com/Forms"> Edited by: Mark Reichman on Aug 18, 2010 1:33 PMAlthough the "upgrade" option does not throw an error, it really doesn't apply any longer. It was used historically to convert SqlForms to Forms Menu Modules. Here is the text from the Forms Online help for this option:
Upgrades modules from Oracle Forms 4.5, or from SQL*Menu 5.0, to an Oracle Forms menu module.You gain nothing from including "upgrade=yes" when you compile your 10.1.2 modules.
Regarding the Module version you see in the XML or FMT, this version represents the engine used to create the module and not the Forms version. This version will not necessarily line up with the Forms version to which you are accustom to viewing. This is more of an internal reference. Your form's modules will not change in any way when you patch from 10.1.2.0 to 10.1.2.2 to 10.1.2.3. This is why there is generally no need to recompile when you patch. The changes are made in our product and not your app. -
CS4 Upgrade and Previous Versions of Photoshop
As a long-time Photoshop user, I have upgraded my versions of Photoshop over the years and currently have the CS4 Photoshop Upgrade loaded on my computer. I have an older computer with limited hard drive space and am running out of room. Is it necessary to keep all the previous versions of Photoshop on my computer's hard drive in order for the already-loaded on my computer CS4 Photoshop Upgrade to run? In other words, can I remove the earlier versions (like Photoshop 4, Photoshop 6 Upgrade, Photoshop 7 Upgrade, and CS2 Photoshop Upgrade) and still have CS4 Photoshop Upgrade run ok? I'm trying to clean up hard drive space and would like to make space by deleting the previous versions, but I don't want to mess up my CS4 Photoshop Upgrade if that program somehow ties into components from the previous upgrades.
Any help would be appreciated. Thanks.Thanks for the response. I currently have CS4 Photoshop Upgrade version already on my computer. In addition to that, I also have on it Photoshop 4.0, Photoshop 5.5, Photoshop 6.0 Upgrade version, Photoshop 7.0 Upgrade version, and CS2 Photoshop Upgrade. What I need to know is can I remove the earlier versions of Photoshop or will it negatively affect the operation of CS4 Photoshop Upgrade (since it's not the full version and only an upgrade of the upgrades installed earlier)? (The only full version of Photoshop I have is Photoshop 4.0 -- everything after that was upgrade versions.)
