Troubleshooting DOORS Next 6.x to 7.x Upgrades todo.png

Authors: PaulEllis, IanGreen, VaughnRokosz
Build basis: Engineering Lifecycle Management - DOORS Next 6.x migrating to DOORS Next 7.x

This article is intended to help troubleshoot your DOORS Next 6.x to DOORS Next 7.x upgrade.

The article is intended to be used in conjunction with Understanding DOORS Next sizings in ELM 6.x to estimate timings when upgrading to DOORS Next 7.x which discusses what tuning will be required for your datasize, with the assumption being that the database administrator (DBA) is a key component in interpreting the advice.

What to monitor during the upgrade

If you are still planning the upgrade, then the pre-gather statistics are a very useful way to gauge if your system is large, medium, or small, in terms of what IBM and other clients have tested against. Your size is somewhat dependent upon your hardware, so also use DB Server used for IBM testing to extrapolate your size and upgrade experience.

Settings in advance of starting the upgrade

These settings are not mandatory for an upgrade to complete successfully. However, for the first Staging system run, it would be helpful to set the following to understand more fully what is occurring in the system at any point in time should an issue arise.

* Javacores - set your javacores to run every 30 minutes. If you experience an issue during the upgrade where you think that the upgrade has hung or stopped responding, javacores are very useful to determine if that is correct or what is actually occurring.
