Vanilla Porter error for IPB 3.4.7

Hello,
I'm trying to convert from IPB 3.4.7 with the Porter tool.
Source:
IPB 3.4.7, PHP 5.3
Destination:
PHP 7.1 (then Vanilla 2.13)
When I navigate to the porter file, I have this error:
Parse error: syntax error, unexpected '[' in /home/webapps/forum/uploads/vanilla2export.php on line 12238
I checked the file, and the line is:
$corruptedRecords = [];
I have no idea if what can be the issue ? Thanks in advance,

I have not the issue with the previous Porter (2.2) and can see the management console of the Porter. Can I use it to import to last version of Vanilla 2.3 ?
Using the 2.3 converter and commenting the section exportUserNotes() works now... (Remember =>no user notes on IPB) according to the Data currently supported per platform.
