Renaming a map

Hi, could you please do me a huge favor? I need to change the name of a map;

Map named '231020_AJBC_T8_E56_' should be renamed '231020_AJBC_T9_E58-59'

Please note there is a map named similarly '231020_AJBC_T8_E56' that should be left as it is (difference is a underscore at the end of the one that needs to be renamed)

Many thanks
