We have changed from IE8 to IE10 and there are many Test scripts which are made in QTP 11 using IE8. So knowing that HP QTP 11 does not support IE10, I had some queries regarding the migration:
Also any other suggestions on this migration will be helpful.
QTP 11 does not support IE10
If we change to UFT what will be the changes in the object repository properties? e.g. will the micclass of an object change?
No. Upgrading QTP to UFT will not affect the script. Your script should run fine.
The same is applicable for IE upgrade as well.
