- The system doesn't currently have an ARID configured, .... Should I configure the ARID in the system prior to performing the upgrade, or just when the system comes up after the upgrade (I intend to do an upgrade via SI)?
No ARID generally means it was licensed manually offline, you can enter the ARID during the upgrade when using SI
- I'm not sure if the system is using Flexible Dimensioning. Almost all the Current dimensions are the same as the Defaults, except for a couple that are smaller than the defaults.
Ive had once where the dimension data restored to default. Take a backup and just make note of the current details
- I know I need to migrate from Classic to Extended database model. There are some pre and post migration checklists, but I can't see any instructions on actually performing the migration?
- Do I perform the pre-migration steps prior to upgrading to 4.0, or after?
The command you are looking for is "MIGRATION PRECHECK", you will need to run this after upgrading to 4.0 but before converting the database
- In the pre-migration checklist, it asks "Are there any outstanding deltas in ops" and says to "Check for deltas in ops." OK, what does that actually mean?
Do you use ops manager? If not it is not a problem
- I've been told to expect some errors to do with the directory. Can I import the csv from 9 to correct these, or do I need to re-key all the entries?
Ive havent had issues here, so cant really answer here
- Are there any other tips or traps I should be aware of? I'll be doing this on a weekend by myself, so I'd like to go in with as much information as possible.
What model of phone system do you have? 3300 MX - stop now you can not upgrade to 4.0, 3300 MXe or MXe III no hardware limitation (Im going to rule out a CX as if i recall it cant run that many users)
I am assuming a single controller?
Do you have any additional services (eg MAS, contact centre, MBG etc, if you do check their requirements and upgrade paths first)
universal ASU or ASU II? (I cant remember if the univeral ASU is still supported or not, ASU II is fine)
Backup, backup, backup
do you have instructions to load the software using vxworx? if it fails you will need to resort to this method (using a console cable)
make sure to run the "upgradebootrom all" command after each upgrade (i think they removed the requirement as of 6 or 7, but better safe than sorry)
when running the "load ipdevice <ipdeviceid1> to <ipdeviceid2>" limit it to 100 devices at a time then when done check the IP Telephone Inventory for offline handsets that may require a manual reboot.
