Inventor 8: FATAL ERROR: Schema Migration...

[rstadler]

Loaded Iventor 8 yesterday and migrated a weldment assembly over. So far so good. Created an IDW of the weldment assembly using IV8. Everything was fine yesterday - I was able to open the close the IDW with no problems. Now this morning, when I try to open the IDW, I get the following message:

"FATAL ERROR: Schema Migration occurring without Schema Version change. Migrating: DLxView"

What is the problem? The IAM opens fine.

More clues... tried opening the IDW with "Defer Updates" option checked and file opened OK (w/ lightning bolts next to each view in the browser). Tried opening the IDW again (this time w/o "Defer Updates" selected) and the file opened OK - just as if the orginal "Migration Schema" error never occurred. Very strange behavior from IV8 and with sunspot activity very low today I'm at a lose as to what to blame this anomaly on.

Did you possibly change anything in the design view, in the
assembly, anything at all?

We did have a report of a similar error message during the
beta testing but this particular problem was resolved in the shipping product.
This was related to design views and newly defined design views. Switching
to one of the default design views helped in that instance.

You mentioning this makes me think that it may be related but
not 100%. Maybe turning off Defer Updates helped avoid this.

If this happens again, I would be very interested in getting
hold of the unhealthy dataset.

I don't recall changing anything in the assembly - even if I did, I'm pretty sure I shouldn't be getting this error. Right now everything seems to be working good (fingers crossed, knock on wood). If this happens again, I'll post a new message under this thread.

Thanks for your response.

Richard, I have a drawing that is doing this now,
and I did not change anything in it.

I posted about it under a different thread. Defer
updates did not help, nor did even

renaming the asm and selecting skip at the dialog
box. Can you work directly

from just the drawing file, or do I need to try a
packngo operation?

I received the
following info on this problem this morning from Richard Rankin, and this
procedure did

work for me and I
was able to then open my drawing and work on it. Posting the info here for
anyone

else who may
experience this problem.

another idw first and then open the troublesome idw it should be OK to open,
save and open it again.

I promised an update if this error surfaced again - well, it has. Weldment assembly was created in IV8, IDW was created in IV8, but upon trying to reopen the IDW after being away for lunch, the "Schema Migration" error showed it's face. As suggested by others, I opened another IDW (radomly selected and probably created in IV 6 or 7) and tried to open the afflicted IV8 IDW, the IV8 file opened just fine. My IDW templete was created back with IV5 and has been continously upgraded with each release. Should I recreate the IDW templete from scratch with IV8?

Thanks for keeping us informed.

AutoDesk's stance is that it should be able to
migrate templates with no problems.

My comment the other day was not meant to cast
doubt on migration.

If you have had (lots) of problems with basic
drawings, we have noted several situations where the template had
issues.

Typically it was a VERY OLD template that had an
imported title block and sometimes a log that came in from ACAD or
MDT.

If you have not had problems, R8 is should not
cause you any.

That said - there does seem to be an issue creating
drawings from weldment assemblies.

This seems to manifest with a "schema migration"
error.

We are working on it...

(not sure why it didn't show up in the
BETA)
