index.php changed to indexed.php

We are having a zencart store which will be migrated to cs cart 4.0.3 at last.



In zen cart the urls are structured as :

.xyz Domain Names | Join Generation XYZ

.xyz Domain Names | Join Generation XYZ

.xyz Domain Names | Join Generation XYZ



ie the main file is "index.php" - same as CS cart.

all of these are indexed in google with high rank in search for our products . So when we move to cs cart , we are thinking of making "indexed.php" main file for CS cart. ie changing -

$config['customer_index'] = 'index.php';

to

$config['customer_index'] = 'indexed.php';



in config.local.php



in this way whenever any visitor clicks on old link it will take to old zen cart ,where the “Add to Cart” button will be disabled and a message will inform the visitor to go to new link



Now what we need to know is that will changing “index.php” to “indexed.php” will have any effect on cs cart in future. Is there anything to worry about before or after doing this or whether this is not advisable

Should same type of “response” expected for queries here. Hope we do not find too many problem with CS cart if this is the case.



Anyhow any idea on above query.
