I would like to change my survey id. Instead of using a six digit random number (e.g. 665786), as the ids automatically generated when I create a new survey, I would like to use just a single digit.

I'm doing it by first exporting my survey to a ".lss" file and then replacing all occurrences of the old survey id by the new one. Then, I import the file and create a new survey with my single digit id.

After executing this procedure, everything seems to work just fine, but I'm not sure if this operation will not cause me any trouble in the future. Many things could go wrong. For example, there could be some feature which I didn't test yet that expects all surveys having six digit ids, or perhaps expect that all survey ids are in a certain range.

I found two threads in whic it has been stated that it was okay to edit survey ids in ".lss" files this way, but they are a bit old, so I'm not sure if they are still valid. The version I'm using is 2.00+ Build 131206.

Many thanks!

I don't remember any issues. But your version is very old.
You really should update the Limesurvey version to the last 2.06+.
On newer versions of Limesurvey you can change the ID when copying a survey.
There is an optional field for "New survey id:"

For archiving I always export the survey to an .lss file which I then give the name of the survey.

Something like: "surveyforjohn.lss".

It never caused a problem for me.
